Hi, I use Nod32 2.12.2. I have advanced Heuristics on. After I scanned my computer I got this message. C:\Program Files\IDM Files\Downloads\Programs\eesetup.exe - probably unknown NewHeur_PE virus  and this... C:\Program Files\Offline Explorer Enterprise\OE.exe - probably unknown NewHeur_PE virus . eesetup is the setup file for Offline Explorer Enterprise. They are definately not viruses. Thanks.
