How does antimalware (anti-malware) work?

Watchdog Anti-Malware program scans, identify and eliminate malware, also known as malicious software, from infected systems or networks.

Antimalware protects a computer system or business network from malicious infections caused by a variety of malware, such as viruses, computer worms, ransomware, rootkits, spyware, keyloggers, etc. Anti Malware can be deployed on an individual PC, a gateway server, or even a dedicated network appliance. Effective antimalware tools include multiple features, such as anti-spyware and anti-phishing tools, to ensure full protection.

What does Anti-Malware do?


Many antimalware programs search for malicious software on a computing device using a list of archived malware signatures (blacklist). The anti-malware program compares the suspicious file with the blacklist of malware definitions and if the functions are the same, it flags it as malware. This is one method most traditional anti-malware programs use. Identifying known malware is effective, but the database must be updated regularly to protect against the newest threats.


Contrary to the definition-based method, heuristics are another method that most anti-malware software uses to identify threats. They determine if the suspicious file is malware by running a series of rules. Based on behavioral analysis. A file or program that is coded to delete important and sensitive system files is flagged as malware by the antimalware program. However, the heuristic method fails as it may result in false positives or sometimes even legitimate programs may be flagged as malware.

A sandbox

Sandboxing is another method that can identify if a program or file is malware. The suspicious file or program is moved to an isolated environment, called a sandbox, which is a secure environment, where it is run and executed to determine whether it is malware. Antimalware software will remove malicious files if they display malicious behavior. This is done without affecting the user experience or the normal operation of the computer. With this method, antimalware protects the system from both known and unknown threats.


The anti-malware program not only identifies malware, but also removes it.
