About This Tech Support Scam

These fake error messages are shown by malicious sites that will put your browser on full screen and display pop-up messages that won't go away, essentially locking your browser.

The fake error messages are shown in such a way as to trick the user into thinking that a virus has been detected on their device. It does this to try and scare Windows or Mac users into calling one of the listed numbers in order to receive support. In reality, though, they will only be greeted with people who are trying to sell them unneeded support contracts and services.

The scammers will typically attempt to get the victim to allow remote access to their device.
After remote access is gained, the scammer relies on confidence tricks typically involving utilities built into Windows, Mac and other software in order to gain the victim’s trust to pay for the supposed “support” services, when the scammer actually steals the victim’s credit card account information.

Microsoft or Apple will never send unsolicited email messages or make unsolicited phone calls to request personal or financial information or fix your device.
Treat all unsolicited phone calls or pop-ups with skepticism. Do not provide any personal information.
Always keep in mind that Microsoft or Apple's error and warning messages never include phone numbers
