How To Remove MacDefender Virus/Malware From Your Mac

Remember the Mac Defender malware which disguised itself as an anti-virus, and tricked users into paying for removing viruses from the Macs? The virus has been on the loose for quite some time now and has managed to infect quite a number of Macs out there.

Here are the steps to remove the Mac Defender malware from your Mac -:

Step 1 – Open up Activity Monitor, and select the option to view ‘All process’ from the drop down list.


Step 2 – Find the ‘MacDefender’ process from the list of running processes, and then click on the ‘Quit Process’ option and finally select the ‘Force Quit’ option.

Step 3 – Now, head over to the Applications folder in your Mac and find the ‘MacDefender’ folder. Right click on the folder, and select the ‘Move To Trash’ option. Empty the Trash folder of your Mac after this.


Step 4 – Fire up Safari on your Mac, and click on the ‘Safari’ option at the top of the screen and select the Reset Safari option.

There might be a possibility that users might not be able to delete the files related to Mac Defender. If so, reboot your Mac into Safe Mode and repeat all the steps stated above.

Alternatively, Mac users can also download and install anti-virus software like Sophos etc. However, some of these anti-viruses might make your Mac unstable or give kernel panics. So I would recommend readers to follow the steps stated above.
