My PC has had some spyware for some time but I ignored it. Lately, I have been getting tons of pop ups and warning messages from Windows of possible viruses on my computer. Running a check showed tons of viruses and spyware. The situation now is so bad that I can't even get on the internet. They want to charge me $199 to clean it up. I am wondering if there is something cheaper, like a virus removal tool that I can purchase that will do a good job of removing spyware and viruses, especially Trojans. I'm running Windows XP. Thank you.
