I don't know where else to post this. I keep getting this popup about adult webpages. It comes in the form of a Signed Program Download with a security warning at first and tells me the certificate is valid and all that(I hope you know what I'm talking about). I click no (meaning I don't want to download it) and then all these click yes to access hundreds of free porn sites comes up and then another popup comes up asking me to save something on my hard drive. This keeps popping up at sites that have nothing to do with porn. For example, I go to www.mlb.com and then this porn thing pops up. I have ad ware and spybot and I've done the searches to rid my computer of this, but ad ware and spy bot obviously don't find this and it keeps coming back. What should I do?
