How To Avoid Mac Malware

Post 85 of 112

New Threats: MacDefender, MacProtector, MacSecurity, Mac Shield and MacGuard

Summary

A recent phishing scam has targeted Mac users by redirecting them from legitimate websites to fake websites which tell them that their computer is infected with a virus. The user is then offered Mac Defender “anti-virus” software to solve the issue.

This “anti-virus” software is malware (i.e. malicious software).  Its ultimate goal is to get the user’s credit card information which may be used for fraudulent purposes.

The most common names for this malware are MacDefender, MacProtector, MacSecurity and MacGuard.

In the coming days, Apple will deliver a Mac OS X software update that will automatically find and remove Mac Defender malware and its known variants.  The update will also help protect users by providing an explicit warning if they download this malware.

In the meantime, the Resolution section below provides step-by-step instructions on how to avoid or manually remove this malware.

How to avoid installing this malware

If any notifications about viruses or security software appear, quit Safari or any other browser that you are using. If a normal attempt at quitting the browser doesn’t work, then Force Quit the browser.

In some cases, your browser may automatically download and launch the installer for this malicious software.  If this happens, cancel the installation process; do not enter your administrator password.  Delete the installer immediately using the steps below.

  1. Go into the Downloads folder or your preferred download location.
  2. Drag the installer to the Trash.
  3. Empty the Trash.
