.NET problem

hello
everytime when I try to debug a program (which uses .NET) I get the error "... has stopped working". Then I click on "Debug the program" and then I get an error like something about JIT debigger. I tried to reinstall the program and tried to reinstall .NET, but none of both worked.

Hello vraagtekenhet,

Before anything else, does this only apply to this program, and to this computer?
To ensure .NET framework is not corrupted, remove .NET Framework, and install it. Also, make sure you are running the latest version of .NET.

The program works on other computer, it's really a problem with the computer. I also get this error when I am trying to open for example the Disk Management. This is really annoying. I already tried to reinstall, I first uninstalled with Revo Uninstaller and after-woods installed again, but it didn't work...

I first uninstalled with Revo Uninstaller and after-woods installed again, but it didn't work... Are you saying that you weren't able to install it again?

Do a malware scan with MBAM, this may seem to be a malware.

The install worked with errors. But I shall run the malware scan.

I ran the malware scan, it found some malware so I removed the malware using the tool. Afterwoods I tried to install .NET 4.0 again but it gave me an error about a corrupt file...
