What is AV Protection 2011?

The Malwarebytes research team has determined that AV Protection 2011 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 AV Protection 2011?

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

How did AV Protection 2011 get on my computer?

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

How do I remove AV Protection 2011?

    If you are unable to do this from the infected computer directly, transfer the file from another computer.

  • Now make sure extensions are shown. To do this, please look here
  • Then rename the mbam-setup.exe: Posted Image to iexplore.exe

  • Now doubleclick iexplore.exe to launch Malwarebytes' Anti-malware.
  • Click the "Update" tab and click the "Check For updates" button.
  • Once the program has loaded and updates were downloaded, select "Perform Quick Scan", then click Scan.
  • The scan may take some time to finish,so please be patient.
  • When the scan is complete, click OK, then Show Results to view the results.
  • Make sure that everything is checked, and click Remove Selected.
  • When disinfection is completed, a log will open in Notepad and you may be prompted to Restart, so please allow MBAM to restart.
  • The log is automatically saved by MBAM and can be viewed by clicking the Logs tab in MBAM.

Is there anything else I need to do to get rid of AV Protection 2011?

  • Your files and shortcuts could be hidden again. Look here to find out how to unhide them, if you don't know.
  • The rogue replaces your hosts file, so you may have to restore the old one. You can find third-party hosts file alternatives at hpHosts or at mvps.org or you can simply reset the default hosts file as outlined here by Microsoft.
  • The shortcut called AV Protection 2011 on the desktop can be deleted if it belonged to the rogue.

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 AV Protection 2011 rogue. It would have warned you before the rogue could install itself, giving you a chance to stop it before it became too late.
