avast! Free Antivirus 2020 is probably the most popular free antivirus available on the market.

It offers complete antivirus protection with a powerful engine that scans, protects and eliminates all kind of threats: worms, viruses, trojans, backdoors, keyloggers, rootkits, etc.

Avast! virus definition are updated several times a day and the cloud technology used assure the fastest reaction in case of new in-the-wild threats.

Generally every malware loads at Windows startup, takes control of important system files and sometimes is too late or too hard to do something after that. This is why, avast! has a boot scanner that can find and eliminate known and unknown threats before loading the operating system.

Avast! includes several shields to offer an all-around security: File System Shield, Mail Shield, Web Shield, P2P Shield, Script Shield, Network Shield and Behavior Shield.

The last one needs more emphasize as it’s a new generation type of protection. It will analyze every process that is running and alert if something suspicious or potentially dangerous is found. Current malwares are more and more sophisticated and the number of them is growing so fast, as relying only on signatures is pointless. This is why, a shield like this is vital.

Last, but not the least, Avast! has also a sandbox module which will isolate in a protected environment every file you consider suspicious or detected by Avast! as suspicious. In this way, every damage it may pose to your computer is annihilated and changes are reverted once you close the offending program.
