What is XJR Antivirus?

The Malwarebytes research team has determined that XJR Antivirus is a fake anti-malware application. These so-called "rogues" use intentional false positives to convince users that their systems have been compromised. Then they try to sell you their software, claiming it will remove these threats. In extreme cases the false threats are actually the very trojans that advertise or even directly install the rogue. You are strongly advised to follow our removal instructions below.

How do I know if I am infected with XJR Antivirus?

This is how the main screen of the rogue application looks:

How did XJR Antivirus get on my computer?

Rogue programs use different methods for spreading themselves. This particular one was installed by a trojan.

How do I remove XJR Antivirus?

Please follow the detailed instructions posted in the next post in this thread.


Is there anything else I need to do to get rid of XJR Antivirus?

  • No, Malwarebytes' Anti-Malware removes XJR Antivirus completely.

How would the full version of Malwarebytes' Anti-Malware help protect me?

We hope our application has helped you eradicate this malicious software. If your current security solution let this infection through, you might please consider purchasing the FULL version of Malwarebytes' Anti-Malware for additional protection.

As you can see below the full version of Malwarebytes' Anti-Malware would have protected you against the XJR Antivirus rogue. It would have warned you before the rogue could install itself, giving you a chance to stop it before it became too late.
