At the network level, malware detection can be done through an antivirus program. Some administrators prefer to use a signature-based antivirus program because it can detect known viruses that are already in the wild.

Other malware may be detected by a heuristic method, which means the antivirus program looks for

suspicious activity. This method can catch new viruses before they are added to the antiviruses' signature database.
