OK, I'm helping a distant family member with a Windows 7 security issue. (Using Teamviewer, which is GREAT.) I'm a Mac guy, so I'm really clueless about PC malware, though I'm reasonably impressed with Win 7 and can get around in it. Their system has been working fine, but (and this is explained to me by someone with practically no computer experience) they got a phone call with a guy telling them that their computer wasn't working, but he could help fix it. They go to their machine, and sure enough there is a message on the screen saying that their browser and e-mail won't work! Huh? The person on the phone instructed them to go to a website, which I believe was for a security product they could buy and ... At this point they called me, and I told them to hang up. Fast. As it turned out, their IE was working fine. In fact, everything seems to be fine. I did a MS Safety Scanner run, and everything was OK. So, um, what were they seeing? I presume they downloaded some malware that self-triggered, and sent a message to the scammers telling them it did. The scammer somehow got the phone number, and even the owners name. Is this a well known piece of malware? Can someone point me to a reference, and especially to removal instructions? Thanks much.
