The Yandex tab opens by itself. The browser itself starts with advertising: possible causes and solutions to the problem

When actively using the Internet, each user runs the risk of contracting various viruses. Even the presence of antivirus programs does not guarantee complete protection against all types of infection, although the risk is much lower. Viruses on a computer behave in a predictable way: they track user actions, steal data, display advertisements, etc. One of the consequences of a virus infection in the Yandex browser is that it opens by itself when Windows is turned on or under other conditions. If Yandex browser starts to activate on its own and display various advertising pages, a virus has entered the system.

The reason for automatic launch may or may not be viral. In the second case, eliminating independent launch is quite simple:

More often than not, everything is not so simple, and the reason is a virus, and it is not enough to remove only the virus itself; the Yandex browser may continue to launch automatically. The reason is that antivirus programs are not able to completely remove the consequences of the virus. A set of procedures to eliminate malicious code and its consequences is the only way to remove the automatic startup of the web browser when you turn on the computer.

How to remove a virus?

It is extremely difficult to fight cunning viruses manually. In this case, you need to acquire assistants - anti-virus programs. They will do most of the work for us. The main task of antiviruses is to remove virus code. Having disarmed the virus, it becomes possible to cleanse all the consequences of its presence in the system.

What programs can we use to remove a virus for free:

How to clear traces of the virus and prevent it from reappearing in the system?

It may be that the Yandex browser no longer opens automatically after the virus is removed, but you cannot stop at this stage. Windows has a “Task Scheduler” utility; almost all viruses are added to it. It works like this: the virus code is added to the scheduler, installing its update daily at a certain time or under certain conditions. If the user removes the virus but does not clear the scheduler section, the virus software is downloaded from the network on its own. Soon it will start doing everything the same as before.

If the Yandex browser starts up randomly, you need to clean up traces of malware:

1. Click on the “Search in Windows” button and enter the phrase “Control Panel”. Next, select the appropriate section.
2. We look for the “Administration” section and go to it.
   
3. Click on the “Task Scheduler” item.
4. Select the “Task Scheduler Library” folder; all processes are displayed in the main window.
5. We find suspicious processes. The most difficult point, since you need to have at least a little idea about potentially dangerous processes. To find a virus, we pay attention to all entries without logical meaning, it can be a meaningless set of letters and numbers. All reputable developers indicate their name in the name of the update: Yandex, Opera, Google, etc. If there is a process with an illogical name or the name of an unknown program, most likely it is a virus. You can find out more about what the process is through a search engine.
6. We remove the virus by highlighting the line with it and in the “Actions” tab, click “Delete”.
7. In the “Do you want to delete this task” window, select “Yes”.
   

Now the virus will no longer be able to recover in the system, but not all traces of it have yet been eliminated. When the Yandex browser starts on its own, the virus often installs malicious extensions and affects the shortcut parameters.

Removing virus extensions

Periodically, when you start your computer, the Yandex browser opens due to background extensions installed by the virus. After cleaning your web browser from malicious plugins, self-activation of the browser should stop.

How to clear extensions:

Another way to get rid of the browser launching due to the fault of extensions is to disable their operation in the background. To do this, follow the link to the Yandex Browser settings and in the “System” section, uncheck the “Allow applications to run in the background...” item.

Restoring the correct shortcut and removing the fake browser

Most likely, now the Yandex browser no longer starts spontaneously, but after manually launching it, pages with advertising open. Changing the settings does not help fix this problem, because the problem is in the shortcut parameters.

Algorithm of actions:

Important! If the “Object” line contains the entry browser.bat at the end, it is a virus. You need to rename it to browser.exe, then click on the “File location” button and delete the bat file.

Correcting the path alone does not always help, because sometimes when Windows starts, a fake Yandex browser opens. Some hackers have gone further; instead of spreading a virus that changes browser settings, they add a modified version of the web browser to the system and replace the real shortcut with a fake one. The user himself does not even notice the substitution.

In this case, there is only one way out - manually go to the folder with the original Yandex browser, create the correct shortcut and delete the infected browser.

We remove the fake Yandex browser if it still starts spontaneously when you turn on Windows:

1. Let's move along the path C:\Users\PC Name\AppData\Local\Yandex\YandexBrowser\Application.
2. We look for the browser.exe file, right-click on it, select “Send” and “Desktop (create shortcut).
   
3. Click on the Search button in Windows OS and enter the phrase “Control Panel”. Go to the “Control Panel”.
4. Select "Programs and Features".
   
5. We find a browser from Yandex that is infected with a virus. We can determine it by installation date and version. Usually the affected browser has an earlier version, for example, if versions 16.0.0.181 and 18.10.0.2724 are installed, we can consider the first version - 16.0.0.181 - to be infected.
6. Select the infected browser and click on the “Delete” button.
   

Resetting Yandex Browser settings

There are other reasons why the Yandex browser opens spontaneously or does not work correctly after removing the virus. Most likely, the essence of the remaining reasons lies in changing the settings of the web browser. Restoring them to their default state will help you quickly remove incorrect settings.

The easiest way to reset settings:

Reinstalling the browser

The method helps to remove all errors associated with browser settings and changing shortcuts, but is effective only in combination with cleaning the system of viruses and their traces in the “Task Scheduler”.

How to easily reinstall your browser:

After a short re-installation process, the browser will start again in a fully functional state. Now the Yandex browser probably does not open automatically, but appears only after a manual launch. For the future, we recommend that you have an updated antivirus in your system, which will protect against the launch of the browser itself and other viruses.

If you regularly visit sites with dubious content or download any programs from there, you can be sure that sooner or later your computer will become infected with malicious software. One day it may happen that after restarting your PC, you will find that the browser has automatically opened along with it, and it immediately opens an incomprehensible link or advertisement. This means that you have become a victim of malware and, naturally, you need to fight it so that your confidential data does not “go away” to someone else.

The essence of the problem

Most often, this happens due to the user’s carelessness and the lack of effective security measures on the computer.

While surfing the web, each of us can become a victim of malware, and it is not always possible to identify them on our own. Most often, they “hide” under the guise of harmless or even useful programs that we download and run. As a result, after launching the executable file, malicious code is activated, which can be written to the system registry, browser settings and startup. Of course, such programs do not show any appearance for the time being, but immediately after turning on your personal computer again, you will see that your browser has also opened, and with it a page with advertising or an unknown search engine. In any case, you need to fight this scourge, since there is a high probability that your confidential data may be compromised (attackers can steal passwords, logins, bank card details, names, etc.).

Reasons for appearance

As for the browser that automatically opens with the computer, most often, in this way, attackers try to increase their own profits by moving the user to advertisers’ sites. On the global network, many services are built on the principle that payment is made by visiting certain pages, and the greater the number of visits, the greater the profit. It also increases the conversion of the site, its indicators for advertisers, and accordingly increases its price. You shouldn’t assume that such software is absolutely safe, because you don’t know what the attacker has planned and implemented in his code. It may have added a feature to automatically send user data. In any case, this problem needs to be dealt with.

What to do when, when you turn on your computer, a browser with a website or advertisement automatically opens

This problem is gaining momentum today, and this is largely due to the fact that antiviruses do not yet recognize this as malware. Of course, you can call a master, but then you will have to pay a good amount for minor work. Therefore, try to do everything yourself, especially since the removal procedure itself usually does not take much time. You can cope with this task in literally one hour.

Cleaning startup

So, first of all, you will need to check your startup settings. Perhaps one of your browsers is located there and therefore runs along with your personal computer. In order to clean “Startup”, you need to do the following:

These manipulations will not be enough; after a reboot, most likely, the ill-fated window will appear again. Don't worry - everything is going according to plan, and the next step is to clean the registry.

Cleaning the registry on your computer

To begin, restart your PC again and when the browser starts, pay your attention to the address bar, namely, to the name of the site that launches first (before the redirect). The thing is that it is the name of the first site that we need. If you don’t have time, then immediately after loading you will be transferred to another one, then restart your PC again and repeat the procedure. By the way, in order not to look in a hurry or reboot your desktop computer several times, you can simply disconnect it from the Internet network. In this case, the browser will open again, but redirection will not occur, and you will see the site that we need. Next, you have to work with the registry itself:

To make sure you are not mistaken about what you are deleting, take a look at the “Value” item in the table provided. Pay attention to the address and if the site name you are looking for is indicated there, then feel free to click on the “Delete” button. Repeat the search until the search phrase no longer appears in the results.

For simplicity, you can use special software that analyzes and cleans the system registry. For example, use CCleaner or AdwCleaner. They are quite easy to use, so no one should have any problems working with them. Let's look at an example of how CCleaner works:

If nothing has changed after rebooting, then you should check your computer with an antivirus.

Antivirus scan

Like any other malware, it also leaves traces, although it successfully masks them. In some cases, files or folders may be found that again and again restore deleted data in the registry. The best thing to do is use your antivirus and check your computer. Let's look at the example of Kaspersky Virus Removal Tool:

After a reboot, the device may begin rescanning. As a rule, it lasts a little longer, but also shows better results. If other advertising files are found, repeat the removal procedure.

Removing a page from the browser

Often, malware stores information about itself in the browser settings. It is for this reason that when you launch, an unnecessary page of some search engine or third-party site may appear. All this information can be deleted and returned to its previous form with your own hands, and you don’t have to worry that you will somehow manage to harm your computer.

First of all, you will need to work with the browser shortcut, since sites often register themselves in the properties. To do this you should:

Pay attention to the “Object” field; if there is any additional information indicated there after Application\chrome.exe, then feel free to delete it. Also pay attention to the “Shared Folder” section, where there should also be no values ​​after the word Application. For best results, do the following:

After this, most likely, when you start the PC, the browser will no longer be activated, but some data from the embedded code may still remain. You can only get rid of them if you manually change the settings inside the web browsers themselves.

If you use Yandex.Browser:

If you are using Google Chrome:

If you are using the Opera web browser:

If you are using Internet Explorer:

If you are using the Mozilla Firefox browser.

This instruction will detail where in Windows 10, 8 and Windows 7 such spontaneous launch of the browser with unwanted content is registered and how to correct the situation, as well as additional information that may be useful in the context in question.

Why does the browser open by itself?

The reason for spontaneous opening of the browser in cases where this happens as described above is tasks in the Windows Task Scheduler, as well as registry entries in startup sections made by malicious programs.

At the same time, even if you have already removed the unwanted software that was causing the problem using special tools, the problem may persist, since these tools can remove the cause, but not always the consequences, of AdWare (programs aimed at showing the user unwanted advertising).

If you have not yet removed malware (and they may be disguised as, for example, necessary browser extensions), this is also written about later in this guide.

How to fix the situation

To fix the spontaneous opening of the browser, you will need to delete those system tasks that cause this opening. At the moment, most often the launch occurs through the Windows Task Scheduler.

To fix the problem, follow these steps:

After all unwanted tasks are disabled, see if the problem has been resolved and if the browser continues to start on its own. Additional information: there is a program that can also search for questionable tasks in the task scheduler -.

Another location, if the browser starts itself when you log into Windows, is autoload. It may also be prescribed to launch a browser with an unwanted site address, in a manner similar to that described in paragraph 5 above.

Check the startup list and disable (delete) suspicious items. The ways to do this and the different startup locations in Windows are described in detail in the articles.

More and more often, modern PC users are faced with a problem in which the browser itself launches with advertising. This phenomenon cannot always be considered dangerous. Most often, the user will be able to cope with the failure on his own. In addition, there are often cases in which the browser is launched at a person’s command, and then various advertising pages and banners open in it. Next we will tell you everything about how to deal with this problem. What features of dealing with the spontaneous launch of the corresponding application are recommended to be paid attention to? How dangerous is the situation?

Settings

As already mentioned, quite often the fact that the browser itself starts with advertising does not cause any significant harm to the computer as a whole. But this does not mean at all that the phenomenon can be ignored.

Spontaneous launch of an Internet surfing application with advertising and banners may be due to incorrect settings. For example, a similar phenomenon often occurs in Google Chrome.

In order to get rid of the phenomenon under study, it is recommended to simply reset everything. It is best to use the special utilities that each program has for accessing the Internet. With their help, it is proposed to clear absolutely all settings.

1. Open the appropriate program.
2. Go to "Settings".
3. Select menu items related to saving data (cache, cookies, history) and format them (clear them).
4. Restart your PC.

Virus

Does the browser launch itself with advertising? The most common reason for this situation is PC infection by viruses. Depending on what type of computer infection has penetrated the operating system, the principle of dealing with the problem will change.

The algorithm of actions in this case boils down to the following instructions:

1. Download the corresponding utility from the official Doctor Web website.
2. Launch Dr. Web Cure.
3. In the scanning settings, select browsers, all hard drive partitions and other media.
4. Scan your PC and applications. The browser must be closed.
5. Wait for the test results. If viruses are detected, clean them. To do this, there are two buttons “Treat” and “Delete”. It is recommended to click on the first one first, and only then on the second inscription.

At the end of the process you will have to restart your computer. Now you can observe the behavior of the OS. Does the browser launch itself with advertising?

Reinstallation

Then you can use one more little trick. Usually it helps if you have only one working browser on your computer. You can 100% remove all settings and parameters of an application by deleting it. Accordingly, some users may try by reinstalling the browser.

The process boils down to the following steps:

1. Open "Start" - "Control Panel".
2. Go to the "Add and Remove Programs" section - "Uninstall...".
3. Wait until all installed software is fully loaded. Find the problematic browser in the list that appears.
4. Select the corresponding line with the cursor. Click on "Delete".
5. In the Uninstall Wizard, check the box next to “Delete all settings.”
6. Wait until the browser is removed. Install it again. Restart the computer after initialization.

This approach only helps occasionally. It is usually effective in situations where the launch of a browser with advertising is caused by a worm or a minor system glitch.

Task Scheduler

But that's not all! Does the browser launch itself with advertising? How to remove this phenomenon? If all previously suggested steps have been completed, it is possible that the virus has already been removed. But its remains are preserved somewhere. They cause the browser to launch.

For example, you can check Windows Task Scheduler. If it contains a task that launches an application for accessing the Internet along with advertising, then the only correct solution is to remove this component.

So, to cancel a malicious task, you need to:

1. Open "Control Panel". She is in "Start".
2. Visit the "Administration" section. Here you need to click on “Task Scheduler”.
3. In the left part of the window, click on the inscription "Library...".
4. Study all the tasks that appear on the right. It is necessary to pay special attention to components with the "When Windows starts" parameter. To do this, you will have to open the "Action" tab.
5. Click on the "Delete" button if the "Action" specifies launching the browser not from the root folder of the application.

This is where all the action ends. After these manipulations, the application for accessing the Internet should work normally.

Autorun

Of course, there are exceptions. If the browser starts on its own and opens ads, you can check Windows autorun. Many viruses are registered here, which makes them difficult to remove.

To bring your idea to life, you need:

1. Press the key combination Win + R.
2. Write msconfig in the line that appears. Click on Enter (“Run”).
3. Find all suspicious documents. It is recommended to focus on the “Publisher” column. Highlight everything that seemed suspicious or dangerous.
4. Select the "Disable" function. To do this, right-click on the corresponding line and click on this command.

A small note - if there is a browser in Windows startup, it is also recommended to disable it. Otherwise, if the virus has already been removed from the PC, the application for accessing the network will open on its own when the operating system boots.

Shortcut properties

What other secrets and techniques can help the user? If a browser with advertising starts automatically, you need to check the properties of the shortcut for this application. This advice also helps in situations where advertisements and banners constantly pop up in an application for accessing the World Wide Web.

What to do? Required:

1. Find a shortcut for a particular browser. Right-click on it.
2. In the functional menu that appears, select “Properties”.
3. Go to the "Shortcut" tab.
4. Pay attention to the "Object" field. It must be scrolled to the very end.
5. Erase everything that was written after the executable file with the name of the browser (for example, opera.exe). Usually, if there are viruses, the address of the opening site is written here.
6. Save changes by clicking "Ok".

In practice, this technique really helps. Only most often in relation to a browser filled with advertising and spam that does not launch on its own.

PC Registry

Does the browser launch with Vulcan advertising or any other? There is no reason to panic. The user must check the operating system registry and clean it. This can be done either manually or automatically. It is preferable to use the second option. We will stop there.

1. Download and run the CCleaner application. This utility is designed to work with the computer registry.
2. In the left menu, select the registry, browsers and all hard drive partitions to scan.
3. Click on the "Analysis" button. After a while it will change to “Cleaning”. Click on this button too.

Additional Applications

Does the browser launch with “Vulcan” advertising or something similar? In this case, you will have to act quickly. Often this phenomenon is accompanied by the installation of additional programs and applications that cause the browser to launch.

To get rid of the problem being studied, you need to:

1. Open "Control Panel" and go to "Uninstall Programs".
2. Find all suspicious applications. For example, "Vulcan".
3. Select programs and click on the "Delete" button.
4. Clear your PC registry.

Basically, that's all. Now it’s clear what to do if the browser itself starts with advertising. If all of the above steps do not help, you will have to reinstall the operating system and format the hard drive.

Many years ago, the Internet was intended to be a source of limitless knowledge. But the world is not without greedy people. A lot of scammers have appeared who are trying to get various kinds of benefits by introducing malware onto users’ computers. Even those who have no problems with PC protection fall for the tricks of such people. What can we say about users who do not use antivirus programs at all. Today I will look at ways to solve the problem when a browser with advertising randomly opens.

This is a common case, so we learned how to deal with this “illness” a long time ago. I already talked about how it almost always misses such viruses. In the same article you can learn about a good alternative. Today I will describe some actions when working with Yandex Browser. But they are also applicable to others, because they are all arranged according to the same scheme.

Why do tabs with advertisements open randomly?

There can be one reason here - you have picked up some kind of malicious software. In the case when, when starting the browser, the Vulcan website or something like that opens, it is necessary to scan the system with an antivirus program.

If your computer is not protected in any way, then it’s time to get a “shield”. Above I left a link to an article where I describe Dr.Web . A very good option, I recommend checking it out. But if you don’t like it, then try to avoid considering free software. Paid applications provide a high degree of security (in addition, most of them are offered at an affordable price).

How to get rid of the consequences?

Even if you clear your system of infection using an antivirus program, some traces may remain that prevent you from working smoothly in the Yandex browser or any other similar program. In this case, you will have to work a little with your hands.

Removing tasks from the scheduler

Unknown sites can open spontaneously using commands created earlier. The Task Scheduler is responsible for these processes. Open Start and start typing its name in the search bar. As soon as it appears in the results, left-click on it (works on Windows 10 and other OS versions).

In the window that opens, search for suspicious tasks scheduled for your browser. If you find something unknown, double-click with the left mouse button. A window will appear on the right side of the screen, in which simply click “Delete”.

Follow this algorithm until you get rid of all suspicious plans. If this doesn’t help and ads continue to appear when you turn it on, let’s dig further.

The problem may lie in the shortcut settings

Some hackers take the simple route: they change the launch configuration of your browser. As a rule, they indicate some undesirable site. Then, when you open it, an unknown page will constantly open.

Fraudsters create a harmless file with a .bat extension, which is not detected by antivirus software as a threat. It’s just that such documents are text files containing a certain sequence of actions. Conscientious programmers use them to simplify some routine processes, but hackers can do evil out of anything.

Fortunately for you and me, this can be treated no more difficult than a common runny nose. Find your browser shortcut on your desktop and right-click on it. In the window that opens, select “Properties”:

Here we are interested in the “Object” field. According to the standard parameters, browser.exe should be indicated there. If you have a file with the .bat extension, then you can assume that you have determined why the advertisement opens by itself.

Well, let's do it. In the same window, click on the “File location” button. The folder containing the file you are looking for will open. To save time, delete it (right-click and select “Delete”).
