Have been receiving several calls from this number over the past few days, so decided to answer it. Same thing - could not understand caller - he said they have been getting messages from my windows system. Wanted me to go to my computer & turn it on. I told him I was at work & didn't have access to my personal computer. Asked for the company he was with. I thought he said PC Garden. When I started asking more questions, he hung up.
"George" called me, too. As soon as I heard his voice, I knew it was a scam (although he sounded more Russian to me than Indian). Happily, i have a Mac and, also happily, I never tell anyone I don't know anything about myself over the phone. My only regret is that I didn't waste more of his time before I told him that he had nothing to do with my computer and not to call me again. I feel sympathy for real telemarketers because cold calling is a rough way to make a living. But for crooks and scammers I have zero sympathy.
