McAfee VirusScan Plus, 12 Month Subscription for FREE for HSBC customers with online banking.
After logging into online banking there is a link towards the bottom which says "Free McAfee® Security download" click on it and follow the links for the free anti virus.
I previously posted the link but it looks like it expires after a which and the code at the end changes when I click on it again.
Suppose you will probably know someone with HSBC online banking who can send you link.
I signed up for me and my girlfriend with same link so it looks like it can be used multiple times.
Normal selling price direct from McAfee is £31.99http://uk.mcafee.com/root/landingpages/afflandpage.asp?LPName=12350_vspmiss&affid=449&cid=23861
Can't really complain that is free!
