In the context of Computer Viruses, a "signature" refers to a unique string of code or a specific pattern that identifies a particular virus or malware. Security software uses these signatures to detect and eliminate threats by comparing files and programs against its database of known virus signatures. Regular updates to these signatures are essential for effective virus detection, as new viruses are continuously being created. In essence, a signature acts like a fingerprint for malicious software, enabling rapid identification and response.

Uses of antivirus?

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.

Should you turn off your computer if you have a virus?

If you mean off as in computer is shut off with no power, then no. If your computer is on but off the internet, it is still possible. If you plug in a thumb drive or an SD card that has a virus on it, or a CD or DVD with a virus on it, then it could get infected.
