Antivirus

Antivirus is a software program designed to detect, prevent, and remove malicious software (malware) from computer systems. It works by scanning files and directories on a computer's hard drive and comparing them against a database of known malware signatures. If a match is found, the antivirus software will either quarantine or delete the infected file. Antivirus software can also monitor a computer's network traffic, email attachments, and downloads for signs of malware. Some antivirus programs use behavioral analysis to detect new and unknown malware by analyzing the behavior of programs and processes running on a computer. Antivirus software is an essential tool for protecting computer systems from viruses, worms, Trojan horses, spyware, adware, and other types of malware.
