Since not one title rids all security threats, you bring up a great discussion point. That is, since there is not one that rids them all, what is the next best choice or choices?
I like Grif's advice at http://forums.cnet.com/7726-6122_102-5509131.html?tag=posts;msg5509131
I recently upgraded my SAS to the latest version; version 5.7.1026 and I read CNET's review of it. CNET said it was dated and didn't get rid of all security threats. The review finally said for those who were considering trying it to move on. I've used SAS for years but if there's another free version that's better I'd like to know what it is and what CNET would recommend. CNET did not mention other security software to try to take the place of SAS.
