And my information like Facebook login, credit card details, email account login and photos stored on my computer is being stolen. I was shocked and terrified at that time. Without thinking too much about the credibility of the alert, I quickly called the phone number on the pop-up alert message. Someone picked up the phone and convinced me to turn over control of my computer to a so-called technician to fix it. He had remote access to my computer for about 3 three hours and I was charged about $ 200 after the problems are fixed. I didn’t realize it was a scam until I searched on Google later. How can I be so stupid?
