Avast Antivirus is one of the most powerful antiviruses. It provides comprehensive system protection by anticipating the behavior of malware. The antivirus is based on a heuristic engine, it interacts with various security screens. The application scans all files accessed by the user, analyzes the security of the requested sites, checks available Wi-Fi networks, monitors traffic (including data in P2P networks), scans attachments in messengers and email clients. Suspicious objects are moved to a special isolated environment that the operating system does not have access to.
Note the presence of a special gaming mode. In case of launching any demanding game, the antivirus automatically suspends non-critical diagnostic processes, thereby ensuring maximum PC performance during graphics processing.

I put a lot of different programs both on the computer and on the phone. In order not to infect the system with viruses, I use Avast - this antivirus reliably monitors all unpredictable actions of downloaded files.
I often visit new places, so I access the Internet from a laptop using unfamiliar access points. Thanks to Avast, I am sure that attackers will not steal passwords to my credit card via free Wi-Fi.
A huge plus is Avast - the program monitors not only open files, but also analyzes system processes at the time of loading the OS, which is why I have been using this antivirus for many years.
By occupation, I visit many different sites. I used to use paid antiviruses for protection, but my brother advised Avast. Its free version also reliably checks websites for viruses, while I save money on licenses.
