hmmm have you scan your computer with your anti-virus program yet. if you dontt have one then i recommend downloading AVG anti-virus from www.majorgeeks.com
install it, update avg, and then run the program and see if it gets rid of your trojans. also download spybot and adware SE and install the as well. update them and run both programs and let them get rid of spyware if you got any.
if you have a virus and spyware problem you should download HijackThis and post a log in the HijackThis Log Help Forum under the "security center". Those guys will get you up and running.
