Ad-Aware is a security software offered by Lavasoft. It comes in four different flavors and the features offered by the software vary on the version you have:
Ad-Aware Plus is the version users can get a 1 year license for free! The promotion is being sponsored by v3.co.uk and will only be open for 24 hours starting March 26, 2010. The promotion will start “from midday GMT, Friday 26th of March 2010 through to midday GMT, Saturday 27th of March 2010″. Take special note that the starting times are in GMT timezone; be sure to calculate what time 12 PM GMT is in your timezone (it is 8 AM EST for reference). Since the promotion has not started yet, I don’t have very much detail on how the promotion will work; the only thing I know is that the link for the free 1 year license will be available via v3.co.uk’s download section starting Friday.
