Almost all files are looked at during a full system scan, so it may take a long time to complete.* Identity Theft Insurance underwritten by insurance company subsidiaries or affiliates of American International Group‚ Inc. However, if your computer is acting suspicious or a new antivirus scanner is installed, it is not a bad idea to run a full scan. To run this type of scan, open the antivirus program, and select full system scan option or right-click a file and select the option to have it scanned.Ī full scan should not be necessary if an antivirus program is running on your computer and actively monitoring for changes.

Full system scanįinally, a full system scan or individual file scan is a manual action taken by a user to scan all computer files. Cloud antivirus requires an Internet connection. By running all detection on the server, your computer is spared additional processing. Cloud antivirus detectionĬloud antivirus detection uses a computer program that collects information, which is then uploaded and processed by a server in the cloud. When executed in the emulated environment, if the program appears to perform destructive or abnormal behavior, the antivirus alerts the user before running it. If a program is suspicious, some antivirus programs can also use sandbox detection, which creates an emulated environment for the program to run and analyze its behavior. However, many programs today need to report to an online server or log keystrokes to prevent online cheating, sometimes causing this type of detection to create false warnings. Below are examples of the types of actions and behaviors that may trigger a warning.īehavior-based detection is a useful method of finding viruses or other malware that attempt to steal or log information. If a program begins to perform strange actions, the antivirus may trigger a warning. If a virus has made it past the above detections, the antivirus analyzes the behavior of programs running on the computer. However, signature-based detection cannot detect new viruses until the definition file is updated with new virus information. Signature-based detection is an excellent way to prevent past known viruses and is the best method of detection without creating a false warning. Today, there are well over 100,000 different known virus signatures that can be used for comparison. These signatures allow an antivirus program to identify past viruses that were analyzed by security professionals. Signature-based or virus dictionary detectionĮvery antivirus scanner has a virus definition file, database, or dictionary containing thousands of known virus signatures. These 'false positives' are minimal, but not uncommon. However, it can also generate false positive matches, which means an antivirus scanner may report a file as being infected that is not infected. Heuristic-based scanning is the best-known method for detecting new viruses. It may also detect known viruses that were modified or disguised, and released into the wild again. Heuristic-based detection can detect viruses that have not yet been discovered. The most common form of detection is a heuristic-based detection that uses an algorithm to compare the signature of known viruses against a potential threat.

Below is a list of the different forms of virus detection an antivirus can use to protect your computer. When these known or suspicious patterns are detected, the antivirus warns the user about the action before they're performed.

An antivirus program protects a computer by monitoring all file changes and the memory for specific virus activity patterns. When a computer virus infects a computer, it must make changes to files, critical areas like the registry, or sections of memory to spread or damage the computer.
