I've clicked on some link and now I have multiple critical viruses. Trojans, key logger variant, etc. I'm not able to access the registry, I think damage has been done to it. What can I do? Reformatting the computer isn't a problem for me. There's nothing on it that I need to keep. Is this the best option? If so, how do I do it?
