Yes that poison ivy trojan is a bleepity bleep bleep to get rid of I have also changed my recommended list of "must have" anti virus, malware, spyware software (in case anyone was wondering).

I really like Avast's boot scan, it's very good at catching the slippery baddies that don't get scanned after the boot sequence has started.

AVG is still a good free anti virus, I just don't think it's as good as Avast.
