hey every body. Just so you know I'm running windows xp. my younger brother went on my computer and I think he visited some... adult sites and now my computer it freezing, slow as molasses and i keep getting pop ups to download "offiicial" anti spyware programs that I've never even heard of and I keep getting the little bubbles in the bottom right of the screen telling me I have spyware and malware, trojan viruses and a worm virus. I ran a scan with norton and it found the trojan and said it resolved the problem. I went to the boot menu and I think I selected it to stop starting up when I start my computer but it keeps coming back. so then I downloaded spyware bot and it told me that I have 359 parasites and infected folders etc. etc. I ran a scan about and hour later and it increased to 457! am I totally screwed or can some one give me hand with this one?
