Anti-virus softwares prevent infections from and remove, malicious programs like viruses, malwares, spywares, and trojan horses. Also, these softwares are able to block malicious websites (phishing), which are setup by scammers to behave like a legit website, in order to trick persons into giving out their personal and sensitive information. This includes username, password, address, PIN and credit card information.
Overall, I think Avast is the best free anti-virus software.
Avast Software (formerly ALWIL Software a.s.) has been around since 1988, making anti-virus products. This is over 24 years of experience in the anti-virus field.
It scans and protects the following:
Instant Messenger (IM)
Avast allows you to do a full system scan before your computer boots up. This helps to remove malicious softwares that are difficult to remove after your system starts up.
It has a AutoSandbox feature which allows Avast to automatically run any suspicious program inside the Avast sandbox at the moment the program is executed. This ensures that no damage is done to your operating system and files.
Avast is the only free anti-virus software to receive the Advanced Plus certification rating from the annual “On-Demand Detection of Malicious Software” test from Anti-Virus Comparatives.
