What is antivirus in computer?

[fatema]

An antivirus is software designed to detect, prevent, and remove malicious software (malware) from computers. It scans files and system memory for known viruses, trojans, worms, and other threats, and can also protect against new, unknown threats using heuristics and behavior analysis. Regular updates ensure it stays effective against evolving malware.
