I just found this puppy in a FAQ link Tech posted.
Is this utility still effective? OK for x64 WIN 7? I saw a 2009 date on it. It has to be the fastest full drive rootkit scanner I have ever used. Scanned my 50GB of data in less than 3 mins.
Avast have it integrated already. It mades a rootkit scan with any scan option you chose
Also 8 min after you boot your comp, it looks for rootkits.
