I'm pretty sure my computer has a virus (I pretty sure it's called Downloader and another called Backdoor) and I've been trying desperately to delete it before I end up completely restoring my system and all my info and programs. My Norton AntiVirus 2007 isn't doing a thing to help so I downloaded ewido, which downloaded AVG. The program installed but when I double-click to run it, or select it from my program list nothing happens. Is it because of Norton or the virus? It's supposed to be compatible with Norton so I assume the virus. Does anyone have any suggestions? I'm at my wit's end and could really use some advice! Is it possible to save my computer or should I just wipe the slate clean and start over. Thanks so much.
