We were having trouble in the past week with all that kind of stuff. Fortunately, never clicked on the fake stuff. What finally worked was to update our Norton, and our Ad-Aware SE was helping and what really took care of the final flashing up stuff from the fake one was to now use mozilla instead of IE. Apparently stuff was sticking along with IE and so our problem now seems to be eliminated. Thank goodness. Never had this happen before but there are tons of viruses out there for sure.
