Could be from one of the ads or someone posted something. Use firefox and its add ons to block pop ups and ads.

Been redirected to a "Security Scanner" several times.

Whatever is causing the virus warnings stopped for a few days, but something new is happening. I've gotten several warnings tonight on a taskmonitorworm.
