I am having outerinfo popups and can not remove them. Symantec antivirus every so often displays a dialog box that indicates Purityscan and Trojan clicker and asks to remove and when I click the remove button it says something like it can't remove it and so I just close that dialog box and some time later it pops up again asking the same. I also have outerinfo popups every few minutes. Really annoying. Please help.
