Removal instructions for CleanCatch

Recommended Posts

What is CleanCatch?

The Malwarebytes research team has determined that CleanCatch 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 CleanCatch?

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 CleanCatch get on my computer?

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

How do I remove CleanCatch?

  • 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 CleanCatch?

  • The shortcut called CleanCatch on the desktop can be deleted if it belonged to the rogue.

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