I'm hoping an expert can help me. I have windows XP pro and have not been able to load any new programs or software onto my system. I can open files like documents and pdf files, but can't open .exe files for some reason. I encountered problems with Norton Internet Security and had to uninstall it for my sytem and browser (Mozilla Firefox) to work again. I had Ad Aware then was finding bugs. Tried uninstalling it with Ad Remove Prgrams but it won't budge. Trying to download another copy but it is an .exe file. I much prefer zip files now, having the problem. Please help me.
