about two days ago my browser started sending me scary messages about all kinds of problems and that I must act immediately. In fact, it insists on calling Microsoft technicians for help, however, I never called and so far the only problem I encounter is those ads, but not anything else. Is it some kind of scam? If so, how do I block these pop-ups?
"Microsoft Critical Alert" – is it a scam?
