Answer:
Viruses and Trojans have signatures written for them. By this I mean, when a virus has been discovered, programmers will write a blocking code that is installed in the anti virus program. When you update your anti virus program this new "virus signature" will be recorded in your anti virus program. Then when the virus comes a calling, your anti virus program will recognize the virus and initiate the blocking code so the virus can not install itself in your system.
So with out the signature of the virus, the virus can enter your computer. So updating your anti virus program daily is very important! Some of the top anti virus programs have a new Technology called Heuristic Technology.
This Heuristic Technology dose not need the signature of a virus to block it. The way it works is Heuristic Technology looks for careerists of viruses and will block it just for looking unusual. This is the way of the future. Hackers are getting smarter, our defence must follow. If you care to read more you can on my site trojanhorseremoval.org
