There are two good programs you can use. Ad-Aware and SpyBot: Search & Destroy. I have both. They both are good for finding spyware in your computer. Lately, there has been problems going around because of several programs starting up. Sometimes, those start-up programs are what cause spyware to pop up. Also, since they are included in start-up... you can't delete them because they are running. In order to delete them, you should reconfigure your start-up so those don't start up. That way, you can get rid of the bad stuff. I admit that I look at porn from time to time. Don't blame me... I'm just human. Anyway, I have the pop-ups in control. I am usually ready for pop-ups so when I see one, I can close it before it even finishes loading. That way, it never finishes and more pop-ups don't appear!
