I have run AVG, spybot search and destroy and 3 or four other spyware removers, but PC-Antispyware keeps coming back after my programs remove a bunch of stuff. My Norton AV keeps picking up a downloader virus, removes it, but it too keeps coming back. Also, some kind of bogus-looking "Security System Protection Control Panel" Pops up at various times along with the PC-Antispyware window. I'm afraid to manually delete anything - any help you can give? I'm good at following instructions. It's really making me nuts after 1 full week of trying. Please help, please!
