A word of caution. There are reports that certain viruses are masquerading as the valid taskmgr.exe file. A common behavior among these viruses is excessive consumption of CPU resources. Users may also see two or more taskmgr.exe processes running in the Task Manager. The other taskmgr.exe process you see may be a Trojan or a virus.

Check the properties for both files. The valid taskmgr.exe file should be located in the System folder and is signed by Microsoft. The file may be a nasty virus or Trojan if found anywhere else.

Run an antivirus scan to check to see if you have any virus infections. Choose a reputable product. Keep your antivirus program virus definition database up to date so that new viruses can be filtered and valid programs can be run without any issue. You should also conduct regular checks with an anti-spyware program to keep malware from invading your system.

And always, always, practice safe internet surfing.
