Twice in the last couple of days, I've got an alert pop-up while using Firefox. It shows to be some online virus scan and tells me that my computer appears to be infected and then starts an apparent scan. I kill it as fast as I can. Yesterday, I mades sure that AVG was updated and did a complete scan. It found no threats., just a bunch of tracking cookies. What is going on??
