If you can't open *any* exe then it's probably a virus/worm. This one is
just one example, there's more that use this strategy:

Most of them accomplish this by editing the following registry key:
[HKEY_CLASSES_ROOT\exefile\shell\open\command]

You can fix this (if this is the issue) by creating e new textfile and paste
this into the textfile:

REGEDIT4

[HKEY_CLASSES_ROOT\exefile\shell\open\command]
@="\"%1\" %*"

Now close the text file and save it with a .reg extension, double click the
..reg file on the affected PC.

If you're lucky the worm is not monitoring the registry key and will not
notice (most of them don't notice) that you have fixed the key. Now
immediately run a virus scanner to identify the worm. Knowing which worm it
is your dealing with is required to determine you strategy to fight the
worm.
