I use windows 7 ultimate x86 edition.
I can not run task manager.Whenever i try to run this....it shows taskmgr.exe is not a valid win32 application. I use kaspersky 2012 antivirus. It does not detect any virus that might cause the problem. I have tried to run task manager from command prompt or system32 directory as administrator, but it shows the same error.
How can i solve this?
