What is Antivirus Suite?

The Malwarebytes research team has determined that Antivirus Suite 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 did Antivirus Suite get on my computer?

Rogue programs use different methods for spreading themselves. This particular one was posing as a porn-video.

How do I remove Antivirus Suite?

Our program Malwarebytes' Anti-Malware can detect and remove this rogue application.

  • Download Malwarebytes' Anti-Malware or transfer it from another computer to the infected one.
  • Reboot the computer into safe mode.
    In safe mode:
    • Install Malwarebytes' Antimalware by doubleclicking mbam-setup.exe and follow the displayed instructions.
    • Once you've installed Malwarebytes' Antimalware, navigate to the Program Files\Malwarebytes' Antimalware folder.
    • Locate the file mbam.exe in this folder.

    • Now RENAME the mbam.exe in there to firefox.exe

    • If you want to avoid some possible problems later, rightclick the file and use the "Create Shortcut" option. Drag the shortcut to your desktop so you can easily start the program once you are back in normal mode.

    [*]After you reboot back into normal mode:

    • Doubleclick the firefox.exe (the renamed mbam.exe or use the shortcut you created) in order to launch Malwarebytes' Antimalware.
    • Once the program window is open, the first and most important part is to UPDATE Malwarebytes' Antimalware first.
    • This can be done via the Update tab > Check for updates.
    • However, when you click the Check for updates, you'll get this error:
      connectioerror.png
      This is because the malware you are dealing with has modified your proxy-settings.
    • To fix this, please leave Malwarebytes' Antimalware open under the update tab, because you have to be fast here for the following instructions..
    • Open your INTERNET EXPLORER (not Firefox or any other browser you use, it has to be Internet Explorer)
    • In your Internet explorer in the menu on top, select Tools > Internet Options > Click the Connections tab > Lan Settings button.
    • On the resulting screen, UNCHECK everything under Proxy server, so it looks like this:
      LAN-settings.png
    • Click OK below to confirm the settings, but don't close the window!!
    • Then, immediately switch to your open Malwarebytes' Antimalware (already open under the update tab) and click the "check for updates" button again.
    • If you were fast enough, Malwarebytes' Antimalware will be able to successfully download the updates.
      This procedure sometimes need another attempt, because the malware automatically changes the proxy-settings again, so that's why you need to be fast.
    • 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.
    • You will be prompted to let the computer reboot, after which the rogue application should be gone.

    [*]Rename the firefox.exe back to mbam.exe and delete the shortcut from your desktop, if you created it.
