Can a virus/trojan/malware/worm etc. reside; 1. In a motherboards Bios, 2. In a hard drive after one wipes the drive with zeros'? I have 'something' that is creating a duplicate Windows file and putting in the Windows\Systen32\Wins folder called "DLLHOST.EXE" and possibly "SVCHOST.EXE" (in all caps) that starts up by itself and starts send data. I use a program called DU Meter and I see this upload activity. I then chexk Task Manager and this "DLLHOST.EXE" shows (again, in all caps) which I notice right off the bat. I can't stop the process unless I boot into Safe Mode. My Virus program (NOD32) see that file, but it can't find what is producing it. I have wiped the drive using the manufactures 'write zeros to the drive', reformatted and reloade the O/S (orginally XP, now 2k), but this is still here. Any ideas as this never happened to me before that I couldn't get rid of the 'problem'.
