One of the most devastating scams on the Internet is called a Tech Support Scam. It's actually a million-dollar industry that's been terrorizing the Web for years now. This type of scam is essentially a phishing attack that tricks you into giving a phony tech support "expert" control of your computer. But that's just the beginning.
Here's how they work:
You'll get a cold call, an unsolicited email, or you'll click on an ad for help speeding up your computer or getting rid of a virus. The goal of these scammers is to convince you to trust them enough to download their malware onto your computer. It could be under the guise of remote login technology or an antivirus suite.
From there, they can take over your computer. You may think they're running remote diagnostics like your company's I.T. department would do. It's all just a trick. They're actually installing malware. It's possible they're stealing your personal info, but it's more likely that they'll "discover" those viruses and charge you hundreds or even thousands to remove them.
