From April 24, 2008 AVG is releasing a free version of the popular AVG Anti-Virus. This version (8.0) contains both anti virus and anti spyware and is the best free option available in the market. Unfortunately the free version lacks proactive scanning of browsing links to block malicious URLs (which contain spam/keyloggers).

AVG free offers fast scanning since spyware/antivirus engines are integrated. Another good thing is that it has a low load on the system.  It also comes with safe search - each time you search online, Safe Search checks the results on the fly to give you an immediate idea of which websites are safe to visit.

The limitations of the free version are,

• No real time link scanning.
• This cannot be installed on Windows server versions.
• No technical support
