Until this breach my system was supposedly protected by Norton SystemWorks and Internet Security which continuously monitored security. I ran a twice-weekly virus scans and kept my virus definitions current.
I am so sorry you had to go through all of this! Here is something I have been using for years and it's really great for removing spy-ware from your computer. Oh.. and it's free! It's called Ad-Aware and you can download the free version on http://www.lavasoftusa.com. They also offer some upgraded versions that you can pay for, but the free one has worked fine for me. I used to use Norton Internet security and from what I remember it didn't have a spy-ware removal tool. Or, if it did, it didn't work very well. A lot of the trojans that can get on your computer these days show up as spy-ware and unfortunately a lot of the anti-virus stuff doesn't catch them. Hope this helps!
