Avast Free Antivirus is one of the most popular antiviruses in our country. In addition to being a very popular antivirus solution, Avast is also reliable, which is confirmed by the results of tests by independent companies, in which Avast is constantly in the TOP. What can I say, I have been using this antivirus on my home computer for many years now (perhaps out of habit, perhaps because I have not had any incidents during all this time). Avast Free Antivirus includes not only basic virus protection, but it also has additional functionality, such as home Wi-Fi network analysis and smart scanning.
