This has probably been beaten to death, but I can't seem to get a straightforward answer through my journeys with Google. For the last week or so I've opened Task Manager and have noticed there were two explorer.exe lines. One about half way up using about 5300k and the other one using 23,000k. I've always been told that a virus or worm can dress itself up with the explorer.exe tag. Now, I've scanned with KAV 2009, MBAM, and SuperAntiSpyware and have found nothing suspicious. My computer runs pretty quick,(4gb of RAM) and steady, so with all that said, Is it possible to have 2 legitimate explorer.exe to be running at the same time or do I need to look further? When I open file on each one they both take me to the same place. I killed the small one once and nothing that I could see or feel happened. What to do?? When I re-boot the smaller of the 2 seems to go away. I hope someone can put me at ease.
