Instructions
Try using Dr. Web Cure It. It does not require installation, and scanning the system begins immediately after launching the exe file. Download this program by visiting http://www.freedrweb.com/cureit. Restart your computer and start the operating system in safe mode. To do this, press and hold the F8 key after starting boot from the hard drive.
Run the downloaded exe file and wait until the program finishes scanning system files. This process can take quite a long time. Be sure to follow the progress of the process. You will be asked to delete certain files yourself or choose another option to deal with them.
If you know which files need to be deleted, then try doing it yourself. If the system does not allow you to completely remove some components of the virus software, then try the “recycle bin” removal method.
If, when you try to delete a file, a window appears with a message stating that this file is occupied by another process, then start the system again in safe mode. If after this you were unable to remove the virus file, then press the key combination Ctrl, Del and Alt.
After opening the task manager, one by one, disable all processes that are not system ones. Never disable a process unless you are sure of its purpose. This may cause the operating system to crash. Try deleting the file again after stopping unnecessary processes and services.
Try performing a system restore procedure. Use a checkpoint that was created before problems occurred or malicious files appeared. This method will help remove virus software if it was installed together with any program.

Tip 3: How to scan your entire computer for viruses
If you suspect that viruses may have appeared on your computer, you need to perform an anti-virus scan. There comes a time when you can see a sign on the desktop of your computer that says that your computer is infected and you will need to download a good antivirus. An inexperienced personal computer user, of course, agrees. But a good antivirus does not want to treat for free and requires sending an SMS message to a specific number, which, as a rule, leads to debiting a large amount from the user’s phone. Read on to find out how to deal with this.
You will need
- Scan your hard drive with specialized anti-virus programs.
Instructions
The whole problem is that previously installed antiviruses, which you did not get, cannot catch such an “infection” on the fly. Other free utilities designed to clean up all sorts of threats that the usual one cannot cope with can come to your aid. An example is the free utility from Dr.Web - Cure It! Installing and running this program will not cause you any difficulties. If there are no viruses when scanning with this product, reboot and enter the mode. Most viruses can block virus scans.
There is also a possibility that the virus has entered the kernel of your operating system. In this case, the antivirus will not be able to find such a virus. In this case, you need to check your hard drive on another computer, which will be clean (previously checked by antivirus).
Sometimes it is enough to use special boot disks. These disks load at system startup and check the most vulnerable areas of your shell for the presence of dangerous elements. Such disks can be found from most modern antivirus manufacturers.

The most reliable step for detecting viruses (and necessary for subsequent treatment of viruses) is to install anti-virus software. The functions of such programs directly include searching, detecting and restoring infected files. Many manufacturers offer a variety of antiviruses. And any computer user can download and install both free antivirus programs (AVG Free, Avast!, Avira AntiVir Personal and others) and, for additional reliability, paid, proven antiviruses (for example, NOD 32, Kaspersky Anti-Virus, Dr.Web and so on.)

Modern hackers strive to ensure that the virus that has picked up your computer works as unnoticed as possible, so that you do not suspect anything and continue to use your computer as if nothing had happened. Then they will be able to steal any passwords you enter, bank card numbers, or send spam from your email account.
Protecting your computer from viruses, Trojans, spyware and other malware is very important. Sometimes the lack of proper protection leads to the fact that valuable information, both personal and official, may be lost or stolen. If for some reason you cannot install an antivirus on your PC, use an online scanner. Let's look at how this can be done using the Panda online scanner as an example.

Instructions
So, go to the company's website and go to the online scanning section at http://www.viruslab.ru/service/check/.

On the online antivirus page, you will see a large green button that says “Scan.” There are also several “submenu” buttons: “Quick scan”, “Full scan”, “Custom scans”. Select the type of scan you need and click on the green “Scan” button.
The program will prompt you to download the ActiveX controls component - you only need to do this for the first scan and the download procedure will only take a minute. After that, click on the “Scan” button again. The process will begin and after a while you will be able to see the result.

It is best to entrust the search for viruses to software specially designed for this purpose - antivirus programs. Finding an antivirus on the Internet is not difficult - the virus problem is not new and very relevant, so sellers of this type of program are very active. Due to great competition, each manufacturer is willing to provide you with a free trial period, which allows you to install and scan your computer with almost any of them.
You will need
- Antivirus program
Instructions
The virus scanning procedure has some differences when using different antiviruses, but there are also common methods, since all of them have to be built into the same operating system. For example, each of them places a command to run a virus scan in the Windows Explorer context menu. To use it, launch the file by double-clicking the “My” shortcut on the desktop or pressing the keyboard shortcut CTRL + E.
Then select the drives that need to be checked for viruses and right-click everything selected. A context menu will appear, which will now contain the command to run an anti-virus scan. Each manufacturer formulates it differently, but the meaning is the same for everyone. For example, if you have installed Avira, then this menu bar will contain the text “Scan selected files with AntiVir”. Clicking it will launch the antivirus utility to scan your computer's media. The duration of this process depends on the total number of files that the program will have to check, as well as on the degree of detail specified in its settings for examining all suspicious signs.
If the program detects something potentially dangerous, it will notify you about it either during operation or at the end of it, and offer a choice of options for actions with the found objects. The degree of antivirus independence can also be adjusted for almost all manufacturers. Once the scan is complete, the program will show a report, regardless of whether viruses were found.
Another method common to all antiviruses to start a scan requires opening its control panel. This can be done by double-clicking the icon of this program in the desktop tray. The control panel will definitely contain a command to immediately start scanning the entire system. For example, in Avira such a link with the text “Check system” is placed on the very first page of the control panel that opens. Next to it is the date of the previous full scan of the computer media.

The Windows operating system, with all its undoubted advantages, has one significant drawback. Namely, it is vulnerable to viruses and Trojans. And although antiviruses and firewalls significantly reduce the risk of infection, the user is sometimes faced with the need to find a virus that has settled on his computer.
Instructions
All destructive programs can be divided into two types. Some of them make themselves known very clearly: for example, they destroy information, display various messages on the screen, and cause disruptions in the operation of the computer. Others, usually Trojan programs, try to hide their presence.
When you encounter the presence of programs of the first type, try to find the program file and autorun key. Open Task Manager (Ctrl + Alt + Del) and see if there are any processes with suspicious names that are not typical for your system. If there is one, write down its name, then “kill” the process by selecting it with the mouse and clicking the “End Process” button.
If the process was successfully completed and the problems with the computer have disappeared - which means that you have completed the process of the destructive program - open the registry editor. To do this, click: “Start - Run” and enter the command regedit, then click “OK”. The Registry Editor window will appear. Open the search: “Edit – Find” and enter the name of the completed process without extension. Delete all autorun keys found.
If a virus hides its presence in the Task Manager, use the Spyware Process Detector program, it can be found on the Internet. It allows you to detect hidden program processes and terminate them. With its help, you can also remove autorun keys from the system registry.
Open Command Prompt: Start - All Programs - Accessories - Command Prompt. Type the command netstat –aon, press Enter. You will see a list of active network connections. In the “Local Address” column you will see open ones currently in use. The “Status” column will reflect the status of these ports.
The ESTABLISHED value indicates that there is currently a connection to the Internet on this port. The LISTENING state indicates that the port is open and the program using it is waiting for a connection. Such a program could be a backdoor - a program that allows you to control your computer.
Remember the PID (identifier) of this program, it is indicated in the last column. Type tasklist in the command line, you will see a list of processes. In the PID column, find the required identifier and see which process it corresponds to. You can immediately “kill” this process with the command taskkill /pid 1234, where instead of “1234” you specify the PID of the process to be killed.
Ports 135 and 445 in Windows are open by the operating system itself. It is recommended to close them with the “wwdc.exe” utility. Always keep track of which programs are opening ports on your computer. Don't work without a firewall. Always enable display of file extensions. Update your anti-virus databases in a timely manner.
