Cannot run any .exe files
Since trying to protect myself against pop-up and junk etc, I installed Microsoft Antispyware Beta, then removed it and since then I've had problems were I can't run any .exe file. Even running MS Office programs won't load. Everytime I try to run a file with the .exe extention, i get an error saying "This file does not have a program associated with it for performing this action. Create an association in the Set associations control panel." I found the panel, but it didn't have the extention .exe for me to edit, what do it do. Please help.
