Just got called from this number by an indian woman. She said at least 5 times you have viruses infecting your harddrive i was trying so hard not to laugh. But finally we got to a point where she wanted me to press the windows key + r and i told her nothing was happening and she hung up...
Same computer scam as reported above. I kept "Larry" (with an almost incomprehensible accent) on the phone until I got bored, and then told him I had been deliberately wasting his time. He hung up.
