I just looked at my ClamAV virus scan results and I found that I had a Trojan horse/Back Orifice dll in my system! Apparently it could have been there for a long time allowing people to control my computer to send spam or other evil things. It was a part of the Filzip program, a freeware utility.I removed the program, but I had been using it for a while. It’s pretty scary since I consider myself to be pretty net savvy. I guess that teaches me to not download every bit of freeware I can find. I guess Winzip will have to handle my compression needs.

Here’s the entry in the ClamAV scan that showed me I had an intruder:
C:/Program Files/FilZip/unrar3.dll: Troj.BO-Server FOUND

Be careful if you have this program, you may want to uninstall it.
