avast 4.5 home has a very wide userbase, and has as good as or better virus and trojan detection rate than norton.. yes i know, the gui sucks. but if u right click and go to enhanced mode. then its much better ( but wait!! its only available through proffesional version) avast 4.5 is relatively new, so cracking groups havent had time to release a keygen yet. if u stick with home for a while, and look around sites for keygen then i am sure u wil get the pro key someday. otherwise u can always look around the torrent sites as they always seem to have the key included .
[eidt[ home edition should be completely free, it should reregister itself once the 14 months passes.
