Rising Antivirus Free Edition

“So far, I think this is the most polished and complete of the free AV’s out there. Antivirus, Antispyware, POP/SMTP protection, Anti Rootkits, automatic updates. Easy interface to navigate. It also got the VB100 award…seems to have everything.”

I agree, it’s pretty good. Of course, AVs don’t really work, but the general public doesn’t need to know that.
