Remove Compromised Windows Security pop-ups (Support Scam)

If you are seeing a Compromised Windows Security pop-up, asking you to call a support number, then your computer is infected with a Trojan horse (Rogue.Tech-Support-Scam).

The Compromised Windows Security alert is shown in such a way as to trick the user into thinking their computer has crashed or that a virus has been detected on the computer. It does this to try and scare the infected user into calling one of the listed numbers (855-616-6772) 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 “Compromised Windows Security” pop-up ads are caused by a malicious program, which is typically bundled with other software that you can download for free from the Internet. When the malicious program is installed, an “Compromised Windows Security” alert will randomly pop-up.
The fake “Compromised Windows Security” pop-up will have this message:

Critical System Failure
Compromised Windows Security
Please Call Technical Support 855-616-6772
Computer ID: 3257-6989
Response Code:

As you can see, this program was created for the sole purpose of displaying fake Windows alerts in order to scare you into purchasing remote support services. If you are infected with this program, please ignore any alerts that are displayed and do not call the displayed number. To remove this Trojan and any related software, please use the removal guide below.
