Task manager disabled

[Catsrules]

My task manager has been disabled, I have tried to enabled it by doing the gpedit.exe thing, but it didn't help.
This is my personal computer that isn't on a domain, so it can't be a domain policy thing.
My OS is windows 7 Pro 64Bit
It is happening on my Laptop Win 7 64Bit as well, so I might be a Virus or a glitch in a program I installed that has caused it. I try keep my desktop and laptop, similar to each other with the software I install on it. But I hasn't happen on my 32bit laptop, but I haven't been keeping that one up with the stuff I install on it.

If task manager can't run it's gotta be a virus. Don't plug in any usb keys, the virus could infect the thumb drive and you could reinfect your self later.
