All EXE are not working Failure

My system has been affected by a virus w32.Yaha.t@mm.
While trying to remove it, i have tried adding a new
extension in Folder Options with extension .exe. It asked
me whether i want to un-associate the current association.
Now I am unable to restore the previous association. And
now, I unable execute any of the exe directly. Some
applications are opening by doing below on any
document "Right Click>Open With>App".

Help me restore the exe file association.

A couple of things to try;

Restore the registry from a recent backup.

or

Explorer|Tools|Folder Options|View and uncheck the box for "Hide extensions
for known file types" then copy regedit.exe as regedit.com Then create these
*.reg files and import;
