I typically do not answer any calls that I cannot identify - but this one called at 7:15 am this morning (a Sat!) and woke me up so the first thing I said/yelled to the east Indian male was, "why the hell are you calling me so early in the morning?" and he just ignored my anger and went on about malicious software from the "server" that is now on my PC. I told him this was BS (using the full version word) and that I know these calls to be scam games and instructed him to take my number off their list. He hung up. Karma will come back on all these people who try to scam others!
Got a call from this number, heavy accent, claiming to be from Windows. I asked for a phone number so I can call them back, knowing they were full of crap, and the man said rudely "Why don't you be straight with me?" Told him off, hung up. He called back two more times.
