Virus found - i know its now

I know the hacks arent viruses and ive been using them for afew weeks.

My antivirus is Avast - Free
It did an update today and now i cant even open PerX.
It just pops up saying its a virus so i CANNOT run it.

WHAT DO I DO

Turning off your AV should fix the problem.

Avast show warning on every unknoun prog.Don't use AVAST. Use KIS 2009.And if you need fresh keys PM me.

Uninstall avast and install Avira, Kaspersky, or AlYac.

Add it to exceptions.

I've had some bad experiences with avast. Uninstall it and download Avira.
It's less of a pain in the ass than avast.
