Today my mother called and told me there was a guy remotely "fixing" her computer. After the phone company came to replace a bad router, a pop-up appeared on her computer and a voice that said she needed to call a number to remove whatever the hackers had done. She called it and then called me after they'd been working on it for 3 hours. I told her it sounded like a scam and that she should probably call the bank about the $580 payment they said she would have to make for their services. I tried to find information on the names they gave her - Tech Net, Digitec Anti-Hacker Team and Chandan Bharti (the guy fixing her computer) - but have been unable to find anything. I did find Chandan Bharti who is a consultant for Microsoft, but that's it. My question is, now that they already got access to her computer, what should I do to check for anything they may have installed on her computer and to make sure they can't continue to access her personal information? Has anyone heard of these company names?
