|Use process explorer to find the source of your taskmgr.exe, perhaps it's not what you think it is:|
1. TaskMgr.exe: Windows NT4/2000/XP/2003 Task Manager. The path for this program is C:\WINNT\System32\Taskmgr.exe or C:\WINDOWS\System32\Taskmgr.exe.
2. Taskmgr.exe: If you are running Windows 2000/XP/2003 and you do not have the Windows Task Manager currently open, or if you are running Windows 95/98/ME, then you have the Trojan.StartPage.G virus, or one of the viruses that masquerades as the Task Manager.
