AVG Technologies released V 9 of their products in October 2009. AVG Free Anti-Virus is available at avg.free.com . It includes AVG LinkScanner for real-time(!) safe surfing, and searching. In the US, it also includes (for those downloading the AVG toolbar) Identity Theft Recovery Unit, in case of identity theft.
