recently my system was attacked by three viruses
1. love.exe.
2. aaa.exe
3. important.exe
they were cleaned using nod32 anti virus
however after they were removed none of the applications seem to work
i tried installing acrobat reader
and it would show rundll32.exe not found
also when i try to run any system tools
it still shows that message
even when i open c:
it shows the same
what shall i do to remove this problem
i have already formatted my system and re-installed windows once.
