Shirley it's a moot point?
Given that there are all sorts of companies (ISPs, banks, you name it) throwing out free copies of full featured security packages who exactly bothers with these feeble attempts? I can have Kaspersky or Mcafee for nothing. And while I don't need either (Linux user) I can't believe there are many people out there who don't have access to something reasonable.
Having said that it may be that some people don't know they can get this free software. I was completely unaware that my bank offered free AV software until I was informed by another customer. Likewise I know people who were unaware that their ISP offered free a AV package.
So the advice to people who are thinking of installing either of these packages, or one of the competitiors, should be to check if they can get a full featured package gratis.
