Ok.. I need help from one of you computer pros!!

I finally ditched webtv and bought a laptop. So, you will probably have to explain like you are talking to a child! lol

I come online through Juno. It has a pop up blocker, and seems to work well, as I don't get many pop ups at all. (Though, most of my online time is really spent here at BK anyways) However, I keep getting these pop ups that dont look like typical ads. They look like messages you get from your computer. (Typical dialog boxes telling you stuff that is going on, like when downloading.. with an OK button, and the typical windows type stuff, the X , minimize and maximize buttons

They are telling me such as "55 critical errors have been found, go to this website, blah blah blah.. " and telling me to go places like 32sys.com, regproscan.net, helpfixpc.com(NOT Microsoft sites like I would think it would). The first time I started getting these, I did visit the site. It wanted me to basically download something that would find things, and I could pay for it to fix them. I also got a pop up saying something about the "certificate" and the site could not be confirmed. So, I did nothing.

A friend said it sounded like spyware, so I downloaded a spy bot ran it and it found a bunch of stuff, and I got rid of it. The pop ups persisted.

Later, I got looking around, and found an Event Log (Start/Settings/Control Panel/Administrative Tools/Event Log)... Lo and behold, EVERY one of these pop ups were logged in there, and called "application pop ups". If I clicked on each individual event, it showed me an exact copy of the messages in the various pop ups.

I then downloaded a virus scan through Microsoft, and it found nothing.

Please, someone must have some advice! These popups are making me crazy. They are coming 3 or 4 per minute sometimes!
