Some scammers call and claim to be computer techs associated with well-known companies like Microsoft or Apple. Other scammers send pop-up messages that warn about computer problems. They say they’ve detected viruses or other malware on your computer. They claim to be “tech support” and will ask you to give them remote access to your computer. Eventually, they’ll diagnose a non-existent problem and ask you to pay for unnecessary or sometimes even harmful services. If you get an unexpected pop-up, call, spam email or other urgent message about problems with your computer, stop. Don’t click on any links, don’t give control of your computer and don’t send any money. If you get an unexpected or urgent call from someone who claims to be tech support, hang up. It’s not a real call. And don’t rely on caller ID to prove who a caller is. Criminals can make caller ID seem like they’re calling from a legitimate company or a local number. If you get a pop-up message that tells you to call tech support, ignore it. There are legitimate pop-ups from your security software to do things like update your operating system. But do not call a number that pops up on your screen in a warning about a computer problem. If you’re concerned about your computer, call your security software company directly but don’t use the phone number in the pop-up or on caller ID. Instead, look for the company’s contact information online, or on a software package or your receipt. Never share passwords or give control of your computer to anyone who contacts you.
