What is MicroVaccine?

The Malwarebytes research team has determined that MicroVaccine 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 MicroVaccine?

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 MicroVaccine get on my computer?

Rogue programs use different methods for spreading themselves. This particular one was downloaded from their website.

How do I remove MicroVaccine?

Our program Malwarebytes' Anti-Malware can detect and remove this rogue application.
  • Please download Malwarebytes' Anti-Malware to your desktop.
  • Double-click mbam-setup.exe and follow the prompts to install the program.
  • At the end, be sure a check-mark is placed next to the following:

    • Update Malwarebytes' Anti-Malware
    • Launch Malwarebytes' Anti-Malware
  • Then click Finish.
  • If an update is found, it will download and install the latest version.
  • Once the program has loaded, 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 MicroVaccine?
  • The shortcut called MicroVaccine on the desktop can be deleted if it belonged to the rogue. If you are unsure compare the icon to the one posted above.

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 MicroVaccine rogue. It would have warned you before the rogue could install itself, giving you a chance to stop it before it became too late.
