Avast 6 defines the Win32:Rootkit-gen

http://www.virustotal.com/file-scan/report.html?id=fc286714691bbb2d1d4d6a62f089e0fb06f3785b759c7c1bc21f81b8b13ca092-1298819997

Question … have not updated the virus database, or method of determining Avast 6 so good?

The definition dates for avast are old (23-2-2011) so that could be a reason.
Not sure why they are not being updated…

Understandable. Thank you. Sorry that I have made a separate topic.
