Supposed "Spyware Blocker" is taking over my computer, how do I get rid of it?

I probably downloaded a faulty song or music video from Limewire or something, and it installed this program (if you can call it that) on my computer. Two tray icons appear and every 2 seconds a balloon pops out of one of them telling me I'm infected with Trojans and need to download their software immediately by "clicking this baloon" (note the spelling on balloon). The other one sends me endless streams of pop-up ads, changes my homepage, redirects me from websites, and is incessant. I actually finally tried downloading the two programs so that the pop-ups would stop, and then I could uninstall the programs. That didn't work. Even though I have the programs, I still get 948576935 pop-ups telling me to download the program quick or my computer will die! I already have Norton Antivirus and in fact, Norton has been blocking some attempts made by these programs. When I right click the tray icons to close them, their website pops up. How do I get rid of these incessant advertisements?

Believe it or not this can be fixed. You need to restart your computer in safe mode. Make sure your Norton Anti Virus is up to date by running Live Update. Restart your computer, again in safe mode and run a compete virus scan. Norton will get rid of your problem. After the scan restart in normal mode. You should be fine. If not, contact Symantec directly.
