Comodo Firewall, rated by PC Magazine Online as an Editor's Choice, constantly monitors and defends your PC from internet attacks. It's easy to install and use and passes the industry's most stringent firewall "leak" tests. Unlike some other 'free' firewalls, this is not a stripped down version but is the full, completely functional product. This free solution comes complete with continual updates that are free forever!

Another well featured program available for personal use free of charge. The download is not 'easy' to find but do persist past the versions you have to buy.
Latest versions seem a little bloated with 'features' you cannot disable. I'd recommend Comodo as an alternative if Zone Alarm features become a nuisance

CCleaner is a freeware system optimization and privacy tool. It removes unused files from your system - allowing Windows to run faster and freeing up valuable hard disk space. It also cleans traces of your online activities such as your Internet history. But the best part is that it's fast (normally taking less than a second to run) and contains NO Spyware or Adware! :)

Another freeby, again they do sell a few versions. Look for Ad-Aware SE Personal Edition
