Hi. I'm running Windows 7 (64 bit), on a Dell XPS Studio 1640, and every time I try to run my task manager, I get this error window: "C:\Windows\system32\taskmgr.exe is not a valid Win32 application." I tried to run this because my Firefox has been freezing, and when it freezes, so does every other program I'm running. I've scanned with Malwarebytes, and it shows nothing. I've tried uninstalling and reinstalling my McAfee total Protection, and that doesn't help. Can't seem to find any info on Google about what to do about this. I have no pop-ups, but just out of nowhere, my internet browsing will get extrememly sluggish, then freeze. No matter when I try to run Task Manager, I get that error, though. Not just when the computer is running poorly. Any help with this would be greatly appreciated.

No. It was a refurbished replacement for a laptop I had that WAS under warranty. Got this one right at the end of thy warranty. This hasn't always done this, though

Do you have any valuable data on the lap top?

Do you have a means to back it all up in case a reinstall must be performed?

I do. But what would cause this to happen?

A malware infection could cause this, as a means to prevent the user of the computer from killing that process.

I would start to see if the easy stuff would get rid of it. Use Malwarebytes and your AV program of choice. Run scans and see if that clears it up.

Well a full scan with Malwarebytes took about 6 hours, and it came up with absolutely nothing. I'm running a McAfee scan right now, but it's gonna have to happen overnight, since the Malwarebytes took so long
