Remove Cyber Security Warning pop-up virus (Support Scam)

If you are seeing a Cyber Security Warning pop-up, asking you to call a support number, then your computer is infected with an adware program (Rogue.Tech-Support-Scam).
Please ignore these “Cyber Security Warning” alerts and do not call the displayed number because these pop-ups are a scam.

Cyber Security Warning pop-up

The Cyber Security Warning 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 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.

Virus Info: A Trojan horse, or Trojan, in computing is a non-self-replicating type of malware program containing malicious code that, when executed, carries out actions determied by the nature of the Trojan, typically causing loss or theft of data, and possible system harm. The term is derived from the story of the wooden horse used to trick defenders of Troy into taking concealed warriors into their city in ancient Greece, because computer Trojans often employ a form of social engineering, presenting themselves as routine, useful, or interesting in order to persuade victims to install them on their computers.
A Trojan often acts as a backdoor, contacting a controller which can then have unauthorized access to the affected computer. The Trojan and backdoors are not themselves easily detectable, but if they carry out significant computing or communications activity may cause the computer to run noticeably slowly. Malicious programs are classified as Trojans if they do not attempt to inject themselves into other files (computer virus) or otherwise propagate themselves (worm).
A computer may host a Trojan via a malicious program a user is duped into executing files or browsing internet. Please contact network administration department at +1-844-245-8878 (TOLL-FREE)

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.
