What is this scam? How do I determine if this is a scam?

Computer security scammers call about your broken, infected, and hacked computer. These scammers claim your computer is busted -- and only they can fix it. They'll ask for a huge payment for their services, and they may even keep charging you for a (completely bogus) monthly "security package." Sometimes, these computer security scammers will try to get remote access to your computer. Once they're in, they take your personal information, banking details, and whatever else they can grab. Computer security scammers love spoofing their numbers -- they will often appear to be calling from Microsoft or Apple! Be wary of anyone offering computer security services over the phone -- Apple and Microsoft will never call you out of the blue to troubleshoot a security problem.
