AVG Free provides a good free antivirus option, that is one of the most popular free antivirus. AVG provides sufficient needs of minimum security through combined antivirus and anti-spyware engines. AVG Free 9 has faster scan and boot times.
One new feature is the Identity Theft Recovery Unit, but for US users only.
Optimizing Scanning Speed
A slider facilitates choosing Slow, Automatic, or Fast scans: the slower the scan, the more comprehensive it is. If a virus is indicated, AVG creates a rescue disk to scan your computer in MS-DOS mode.
Advanced Link Scanner
The Link-Scanner feature scans links and gives you advanced protection from third-party malware before the page loads in your browser.
The program doesn’t burden your system when scanning or during background run, although it slows down booting time, and takes time to shut down. AVG isn’t the fastest or most efficient, but it delivers the goods. Download AVG.
