First of all, get an AV that actually knows when a trojan is comin in. An antivirus that monitors network traffic, blocks network intrusions and attacks and all that ****. I'd recommend Kaspersky Internet Security either 2010 or 2011. This is the best av ive ever tried. Also if u dont want to buy licences go to http://www.hack-home.net there you can find key files for it.
Enjoy!
