Try clamXav. However, note that this app is not Tiger ready. I also do not run AV. I feel for other Windows users, but believe that it is their responsibility to take care of themselves. In other works, I don't want to bog my system down because of the lack of personal responsibilty of others. The only exception would be if I were a business and had Windows customers. But, protecting them also would be in my self interest.Scottfab said:Yeah, but I'm sure any Virex will be a system hog. Having the background Virus Shiled naturally seems like a cpu hog, and is almost always unneeded. If anything, I should be able to set it up to only scan downloaded files I choose.
