Antivirus application uses two techniques to search system for malicious activities and viruses
1. Antivirus Examining files and search for the known information or code from the virus dictionary available with them most of the antivirus uses this approach. Antivirus program update its database frequently for the provider website for keep it updated with new virus information. This helps in keeping data secure from the new viruses in the market.
2. Some Antivirus applications examine the suspicious activity of an application and then examine it for malicious code. It checks applications behavior rather than checking for definition it flagged the application and asks user what to do with it. Who antivirus follows this approach provides user protection against the viruses that are currently not listed in the virus database however it also show many false alerts too.
3.Antivirus Examine the program and emulate the beginning of the code of each new executable that is being executed before transferring control to executable If the program seems to be using self-modifying code or otherwise appears as a virus However, this method results in a lot of false positives.
4. Yet another detection method is using a sandbox. A sandbox emulates the operating system and runs the executable in this simulation. After the program has terminated, the sandbox is analyses for changes which might indicate a virus. Because of performance issues this type of detection is normally only performed during on-demand scans.
