What is Personal Security?

The Malwarebytes research team has determined that Personal Security 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 Personal Security?

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

You will find these icons on your desktop and in your taskbar:

How did Personal Security get on my computer?

Rogue programs use different methods for spreading themselves. This particular one uses a fake online scanner.

How do I remove Personal Security?

Our program Malwarebytes' Anti-Malware can detect and remove this rogue application.
Since Personal Security blocks access to our site and blocks the process mbam.exe these instructions will be slightly different.
  • Please download Malwarebytes' Anti-Malware to your desktop.
  • Double-click mbam-setup.exe and follow the prompts to install the program.
  • Then click Finish.
  • In the folder you installed Malwarebytes' Anti-Malware, usually C:\Program Files\Malwarebytes' Anti-Malware, find and rename mbam.exe, for example to explorer.exe

  • Doubleclick the renamed file and once the program has loaded, make sure to get the latest updates.

  • Then select the Scanner tab, select Perform quick scan, then click Scan.
  • When the scan is complete, click OK, then Show Results to view the results.
  • Be sure that everything is checked, and click Remove Selected. Reboot your computer if prompted.
  • When completed, a log will open in Notepad. The rogue application should now be gone.

Is there anything else I need to do to get rid of Personal Security?
  • No, Malwarebytes' Anti-Malware removes Personal Security 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 Personal Security rogue. It would have warned you before the rogue could install itself, giving you a chance to stop it before it became too late.
