Cyberdefender - free internet security suite
Seems ok on the website - http://www.cyberdefender.com/ although i dont know how well it might go in a school. however for home or those many "friends" that "just need a few things sorted" this might be a good priced piece of software.

You can add it to your existing Internet security tools for an extra layer of safety, or you can use it to protect our computer on its own.

Just as long as it isn't malware itself.
Beware of free luches breathlessly announced ;)
