I had somehow picked up a trojan that Bitdefender couldn't get rid of but was able to find a removal tool by them and it looks gone.  The Antivirus doesn't see it anymore anyway.  The only issue remaining is that the Autoscan keeps turning itself off.  When I log on to the laptop I have to turn it back on.  I am worried that it's happening because the trojan is still lurking somewhere that Bitdefender doesn't see.  I completed a system scan with nothing detected.  Please help.
