I received a call from this number. The caller (with Indian accent) said they had been receiving numerous reports of errors from my computer. I strung him along as he directed me to the event viewer. He asked me how many messages I see there. I told him there was only one and it told me that a caller was trying to lead me into trouble. He then said, "I can see that you are a bloody mother f***er" and hung up. He then called right back and uttered more profanities. I hung up. He called back several more times and I hung up immediately every time.
A friend got one of these calls and they talked him through giving remote access. They then proceeded to download a program that disabled his computer and displayed a message that said he needed to pay a $200 license fee to get the computer operational again. This is extortion, plain and simple.
