Kaspersky Anti-Virus 2011 for Mac killing my Mac

Ever since I switched to OS X, I have never really paid much attention to viruses or trojans, but one can not overlook at times the feeling of “uneasiness” by not having antivirus installed.

I tried out the latest version of Kaspersky Anti-Virus 2011 for Mac on my MacBook Pro (2011 with 8GB RAM) and although I did not find any malware, trojans or viruses, the biggest “virus” for me was Kaspersky itself.

Kaspersky Anti-Virus for Mac does not shutdown

In order to scan for viruses, Kaspersky installs kernel extensions and I found that after installing the application, my MacBook (running a 480GB SSD drive) would not shutdown at all. Deleting Kaspersky (which then invokes CleanMyMac to delete preferences) by moving it into the trash, also did not resolve the problem.

I found today, that the only way to completely remove Kaspersky (and it’s kernel extensions which have been the cause of OS X not shutting down) is to remount the install DMG and then select the uninstall option.

This completely resolved the problem and my MacBook Pro now shuts down in 3 seconds as I was accustomed to.

    Informative article. I have also found the guys from Phoenix Software (www.phoenixsoftware.co.za )  great when it comes to dealing with Kaspersky. They are available to talk to on Facebook (www.facebook.com/phoenixsoftware )

    Dear guys,

    Same for me, each time my macbook pro (i5, 8GB, SSD 512GB) has been falling doe dramatically, it is because of Kaspersky file scanning. Same when you want to run time machine, you have to turn it off.
    How to remove this B…sh… app?
