Antivirus programs can have many differences between applications or they can be very similar. There are programs that can be paid for or programs that can be acquired for free. Because having an antivirus program installed to protect the computer and its user is essential for optimal performance and online safety, a program must be evaluated to make sure it fits the requirements for each user’s need and that the computer meets the software’s requirements for installation. One such antivirus program that provides users with real time protection against viruses and protects the user’s sensitive personal files and information is AVG Antivirus.

The internal workings of AVG Antivirus include a scanning engine that scans the user’s files and folders then determines if they are infected with a virus by using its known virus detection. It uses a couple of different virus detection techniques which include generic detection and heuristic analysis. Generic detection effectively finds macro-viruses and script viruses and also looks for variations of known viruses. Heuristic analysis utilizes two different methods, static and dynamic analysis. Static analysis looks for suspicious data constructions and dynamic analysis looks for code emulations.
