Avast 2017

Once the file has been analyzed, the Avast team provides the user with information about whether the file is dangerous - this mechanism allows for faster response times to emerging threats, and also makes a major contribution to improving overall Internet security.

Along with standard protection, the Nitro release is equipped with the following features:

Reduced impact on the system
- With this version of Avast Antivirus, your computer boots on average 11% faster. The antivirus download speeds up due to the smaller program size; security analysis in the cloud frees up the processor's processing power for other tasks. According to an independent study by the testing laboratory AV-Comparatives, Avast affects the system half as much as Windows Defender installed on Windows 10.
CyberCapture
- CyberCapture technology, developed by Avast Threats Labs to analyze unidentified files, protects and alerts users to new threats. This allows Avast's team of virus analysts to provide real-time protection against any new threats before they appear.
Monthly updates
- Avast releases monthly software and component updates to improve threat detection and security. Updates happen automatically.
Scanning HTTPS traffic
- Avast web shield scans all HTTPS sites for malware. Today, about 30% of all Internet traffic passes through HTTPS. On average, Avast detects 50,000 infected unique HTTPS URLs every day, and protects approximately 3.2 million users each month from downloading malware or accessing HTTPS sites that distribute malware. An independent study from Concordia University in Montreal, Canada, found that Avast offers the most effective HTTPS traffic scanner.
Upgraded home network security
- The Nitro update offers improved router security, which includes detection of 12 additional types of vulnerabilities and protection of users from threats such as DNS spoofing, banking hacks, and complete protection of network drives and routers.
Improved SafeZone browser
- SafeZone browser has become available to all users of free and paid Avast antivirus products. In the new version, the browser works even faster, protecting user privacy by automatically moving sessions into an isolated environment - for absolute privacy when browsing, shopping and banking online. The browser offers more comfortable navigation and contains an ad blocker.

2013: avast! 2014

Referring to their own data, Avast developers reported that in February 2011, the installation base of their antivirus was 7.27 million users. This number, according to Avast’s explanation, included only those copies of the antivirus that requested an update to the database at least once in the last 30 days.

If Avast's own calculations are correct, this means that the market share of the free antivirus has grown by about 56% over the past year, up from 4.6 million in the first half of 2010.

The main difference between the Avast! 6.0 included the inclusion of AutoSandbox technology for launching suspicious applications and opening suspicious files in an isolated virtual machine, and this technology will be available even to users of the free version of the antivirus.

According to the developers, the future product avast! 6.0 will be the world's first antivirus to offer virtualization support in a free version. AutoSandbox virtualization technology allows you to create a secure boundary between known dangerous and known safe content. Combined with powerful traditional antivirus technologies, avast! 6.0 should provide users of paid and free versions with the highest level of threat blocking.

To turn on the test virtual machine, just one click is enough - after that, all suspicious files are opened in this virtual machine. If the open file turns out to be malicious, the virtual machine will simply stop, but the user's main computer will remain undamaged. A user of AutoSandbox technology has three options for dealing with potentially dangerous files: run the file in the AutoSandbox virtual machine, run the file without virtualization, or completely cancel the action of opening the file.
