Task manager in windows xp system is not working properly. When i press CTRL + ALT + DELETE to view the process running in background it shows nothing. I can't open task manager from run. The TASKMGR.EXE file for task manager is available in system but when i click on that file error message with pop up comes "Specified path does not exist". Is there any virus which shows message "Specified path does not exist". Any recommendations and suggestions are appreciated.
