I have used Stopzilla before and I liked it because it has real time protection. Another one that is very good (and it has a free edition) is Antivir. This is the one I am using these days (www.free-av.com/). Also, you can find some other spyware /virus protection programs on my website. These ones are either totally free or you can get a free trial without much hassle. Here is the link if you like to take a look: www://computerhelpers.vpweb.com/Free-Tools.html Trudy
