Tech support scans are becoming more common with fraudsters looking to steal your personal and financial information.
Scammers use phone calls, online ads, or email and claim their tech support are trying to fix your computer.
They may ask you to install a remote tool to take control of your PC And ask for your passwords and payment.
If you get an unexpected call from someone claiming to be from a tech company, like Microsoft or Apple, hang up.
Don't trust caller ID, as that can also be spoofed by scammers.
Don't click on links from emails or pop-up messages that claim you have a virus or computer problem.
And never share your passwords or personal details with anyone who contacts you.
If you do have an issue with your computer or security software, contact the manufacturer directly by looking for the real number through their official website.
You can also report any tech support scams to the FTC through ftc.gov/complaint.
