I have used the home edition (freeware) for years as have many companies... this is one awesome virus/spyware/worm/trojan/malware program. With daily virus profile updates free and everything else, it is just too good. And, if you click on something and there is something there, it will not let it into your computer and a little popup window/warning wants to know if you want to let it in, quarantine or delete it. Absolutely the best thing going.
