Free Kaspersky antivirus from AOL
http://www.activevirusshield.com/ant...eav/index.adp?
Free, available to all. You do not have to be an AOL member! You do have to furnish a legit email address so that you can receive the activation code.
It's a very mildly stripped down version of Kaspersky 6. (No Web Antivirus, no Proactive Defense and no Trusted/Exclusion zones. All of which IMO, are not must haves.)
There is a screen during the install that asks if you wish to install an AOL browser toolbar (which I would not do.)
IMO, this would be a much better free alternative than any of the existing real-time capable freebies (AVG, aVast!, AntiVir.)
