The good news is that it is Kaspersky based. The bad news is that "free" is a relative term. According to the article you have to agree to terms like this:
"Active Virus Shield collects a host of information that may be used for marketing purposes, starting with the e-mail address required to download and run the product, according to the fine print. Other data collected include usage stats, responses to ads and details about the PC, according to the AOL agreement."
I'd rather pay for my anti-virus with cash up front. That is a much lower price than what AOL wants for it.
