weird virus in my computer, antivirus wont detect.

When i opened task manager i found a serious of processes running that had numbered names eg. 4197.exe 95791.exe etc. About 8 of these processes start upon logon and they all use the same amount of memory. when these files are running in memory they appear in C:Documents and SettingsKyleStart MenuProgramsStartup. The reason i believe this file may be a virus is that when i right click> properties on the file, under internal name it says worm2.exe. ive tried scanning these files with Comodo antivirus suite but it doesnt find anything. Somehow the virus is adding these files to this startup folder and renaming them. i really have no idea how i would remove this or anything about it. i dont know what else to include. i could get screen captures if that would help. thanks for any advice this is really confusing me.

Is not installed, then Google for that name ( worm2.exe )and see if there are any threads that seem similar to your situation.
