Now if I were more of a vampire this could be intrusive. :-) Sandi ----- Original Message ----- From: "~OoO~" <SirTroth@xxxxxxxxxxx> To: <pctechtalk@xxxxxxxxxxxxx> Sent: Saturday, April 25, 2009 1:45 PM Subject: -=PCTechTalk=- Re: AVG > Yep, the manual or auto system scan, that scans your entire system.
