Definitions for Detection - Viruses work by placing bits of code onto separate files, infecting that file before moving on to the next one. This is why, unlike humans, computers are healed of viruses by cutting off the infected part. The code that viruses place on the file has a unique signature that antivirus programs can spot. This method of finding viruses is very common but has one drawback—the antivirus program is only as effective as it is current. Every time a new virus comes out, the program has to be updated.

To solve this problem, some antivirus programs use a “heuristic” algorithm. Viruses have behaviors in common with each other, such as working without changing the recorded “last modified” date, or avoiding changing the size of the file. The antivirus program will recognize this behavior and find the virus by tracing back to the source. Other antivirus systems use a “baiting” system, where several files are made to look and coded to be like regular files, but are in fact closely watched by the antivirus software. If a virus tries to modify these files, the software catches and contains it. Of course, the cat and mouse game between the virus creators and virus destroyers is endless. Viruses are constantly evolving to dodge tricks put forth by antivirus programs. Top 5 Virus Protection Software Programs
