ok there are several ways an anti virus program works.

firstly and most commonly it look for files on your computer with 'bad' names. ie, names of know viruses. a list of the newest 'bad' files is downloaded from the anti-virus server very frequently. when the AV (anti-virus program) finds a bad file it will try to delete it, and if it cant delete it, it will put it in to a state of quarantine. meaning that the file cannot be acessed but any other programs.

The second way a program will fight viruses is to whatch all the ports on your computer to see if any program is trying to either get in to or out of your computer. if it detects what this program is trying to do is malicious then it will stop it from acsessing your computer.

The third and final way AV stops viruses from harming your computer is to look in memory and for any processes running that and doing things they shouldnt be. like making 'bad' files, removing other files or simply trying to download things you dont want, or even sending your information to some one else.

these are the basic ways VAs i hope this helped you to understand how they function a bit better
