On my old XP box (software part is old only, hardware is upgraded time2time) i have Norton Antivirus.
On my Dell Lappie (Win 7 prof) i'm using MS Security Essentials.
None of the above could detect the Wordpress/Joomla malwares. (though my Norton is not upgraded, only its virus def. are updated, so i can't comment on new Norton versions)
In my Office PC it has Kaspersky and it can detect and clean/remove these malwares.
I'm thinking of purchasing Kaspersky for my Desktop & Laptop.
Any better thoughts?
