  • Detects suspicious behavior from any computer program.

If a bit of code in the file matches with that of the virus in the dictionary, then the antivirus software can either delete the file or repair the file by removing the virus or quarantine it.
  2. Suspicious Behavior Approach: The antivirus software monitors the behavior of all programs instead of identifying the known viruses. Whenever a programs with suspicious behavior is found, the software alerts the user and asks what to do. The system proves to be a little more effective in the advent of a new virus.
