Recently I discovered on 2 of my computers that taskman.exe was showing Explorer.EXE instead of Explorer.exe as a running program. I was wondering if I should be concerned about this. The operating systems on those computers are WinXP PRO and HomeXP. Both computers have Avast5, Malwarebytes Anti-Malware, Spyware Terminator, Spybot Search & Destroy, Spyware Blaster And Comodo Internet Security Suite (Without The Antivirus Option) installed with latest updates. Both computers scanned daily, no problems detected. Both are running quite well.
