Anti Virus Techniques Jordan & Ryan
Use of Checksum The Binary for key files is added up to a number especially in the boot files When these files are called up to do a checksum they are cross referenced with what it should be
Searching for virus signature A virus signature is a unique pattern of bits within a virus The problem with this is that your antivirus software needs to know what it is looking for or else it will go unnoticed as it scans for a specific number This is why software needs to be regularly updated as new codes are added all the time
Heuristic Detection Heuristic detection is a method of finding viruses. Heuristic detection is a less precise method of virus detection than any of the others in this section, heuristics allow rules to be set up to detect new viruses that they have not seen before.
Memory Resident Monitoring This software loads into the computer when it is started up and stays in the computers memory until it is shut down again. May slow down running of programs BUT viruses will be always be detected
