It's a scam call. I've gotten so many of these, it's ridiculous. I usually stop them when they say they're from technical support.
Um...what company's technical support? Oh. Right. They don't HAVE a company. They also don't have any way to access your computer.
I got two of these the other day. I usually argue with them and ask them how they sleep at night being so evil (no kidding...I've gotten so many of these, I tend to get a bit upset). So finally, I decided to take another tact. On the first of the calls, I asked the guy 'if I told you I had Linux, what would happen?' I never said I had Linux, but just asked the question.
The guy stopped and said, 'we dialed a wrong number.' He couldn't wait to get off the phone. I told him to never call me again, yada, yada, yada.
Within an hour, I got another call from the same company. I just hung up because my husband had come home and I didn't want him to hear how I treat this company.
I wish I were as creative as this guy, though. It's a great listen, and some day, I'm going to aspire to what he said.
