Can't open any programs after malware removal

After I've removed an unknown malware with Malwarebytes’ Anti Malware I noticed I can NOT open ANY program…instead I’m getting a pop-up message

“Choose the program you want to use to open this file”

I’m using 7, 64 bytes system and the issue is limited to only one user, the one I use for usual Internet navigation. I could simply delete the faulty user but I like the settings I have for and I would rather not do it.

The administrator user is not affected.

Can you help me out please?

Thank you for your help...After some additional research finally I have solved the issue!

Here is how:

For Windows 7 Users:

1. Have a google search for the file Default_EXE.reg. Sorry I don't have a hyperlink...You may find a .zip file or directly .reg file

2. Save the file to your desktop, unzip it if necessary, then extract (drag and drop) the .reg file to the desktop.

3. Right click on the Default_EXE.reg file and click on Merge.

4. If prompted, click on Run, Yes (UAC), Yes, and OK.

5. Restart.

Good luck!
