How does antivirus software work?

Antivirus software works by scanning your computer or device for known malware and suspicious behavior. It does this by comparing the files on your computer against a database of known malware signatures. If a match is found, the antivirus software will quarantine or remove the infected file.

Antivirus software can also use heuristic analysis to detect previously unknown malware. This is done by analyzing the behavior of files and programs on your device to identify suspicious activity that may indicate the presence of malware.

• Internet security suites: These are comprehensive security programs that offer protection against a wide range of online threats, including malware, phishing attacks, and identity theft.
