AVG Antivirus is one of the most popular anti-virus and anti-spyware software used by millions of users.
The free edition is available only for home and non commercial use on a single computer.
Bear in mind that AVG Anti-Virus is not an all-in one computer protection package.
Rather, it is only for anti-virus use, so without a firewall or antispam feature you will need to seek out other programs for full protection.
If all you are looking for is a free anti-virus tool then it is a must-have, but if you are looking for an all-in-one malware solution AVG Free is not for you.
