How to Remove MaCatte Antivirus 2009 | Removal Guide

MaCatte Antivirus 2009 is a rogue antivirus application that hopes you will mistake it for the popular McAfee antivirus. Their look and feel is very similar to that of McAfee, but as most rogue antivirus applications it is a program that will give you little more than falsified warnings about non existent threats to your computer and then claim to not be able to fix any of the problems unless you purchase. Of course, it really doesn’t do anything because all of the things that it has warned about are made up phantoms. Read on for how to remove MaCatte Antivirus 2009.

Among the falsified warnings you may see from MaCatte Antivirus are the following:

Spyware activity alert!
Spyware.IEMonster activity detected. It is spyware that attempts to steal passwords from Internet Explorer, Mozilla Firefox, Outlook and other other programs, including logins and passwords from online baking sessions, eBay, PayPal.

To remove this you may try through the control panel (add/remove programs) but even if that is successful I suggest using a tool such as malwarebytes antimalware and a trusted antivirus (trend micro/avg/avira/etc..) to review the system again and make sure it is clean. You may download malwarebytes antimalware from a link on my virus removal toolkit page. While you’re there you may want to also download process explorer as well.

If you are unable to install and run malwarebytes antimalware you may 1) reboot into safe mode and re-attempt the installation, updating (safe mode with networking needed for this) and scanning or 2) rename the installer file from mbam-setup.exe to something else like ernie.exe and then retry the install or 3) follow along with the manual removal step below which will have you kill off running processes associated with MaCatte Antivirus 2009 and then retry the installation after that step.
