Hi! I have heard few words about technical support scams, so I have a suspicion that some kind of a virus is trying to involve me in this affair. My web browser is showing Onlineantivirus.net ads that warn me about virus infection. I’m provided with a number of Windows technician. Should I call? If not, what should I do? Please help urgently as Onlineantivirus.net pop-ups are showing more and more often.
