Possible Duplicate: What to do if my computer is infected by a virus or a malware? Why do I always find the strangest programs and the strangest text files all the time? All kinds of weird things happen, like my screen changes and the address line doesn't change in IE, just weird stuff. Is it me or could there really be something going on? I've never had so much trouble with any computer before and I am on a public access point where I live. Any advice will be greatly appreciated. I either need peace of mind, or a good defence, because this is getting out of hand.
