Migue A E :
This doesn't seem legit...how do I stop this pop up from appearing???
If you don't already have one, I recommend installing an antivirus engine (
Avira has a good free option, or
ESET if you want to spend some $). If the popup keeps coming back, consider using the free
GEARS tool for a more thorough scan.
GEARS won't fix the virus per se, but it does use a bunch of antivirus programs to see if one of them will catch the virus where others have missed it.
