Antivirus software app is a program designed to protect your computer or mobile device from malicious software, also known as malware. Malware includes viruses, worms, Trojan horses, adware, spyware, and other types of harmful software that can compromise your security and privacy. Antivirus software scans your device for malware and removes it to keep your device safe.
How does Antivirus Software App work?
Antivirus software works by scanning your device for malware. It checks files, emails, and downloads for any signs of malicious software. If it detects malware, it will either remove it or quarantine it, depending on the severity of the threat. Some antivirus software also includes real-time protection, which continuously scans your device for malware and blocks it before it can do any harm.
Antivirus software uses various techniques to detect malware. One common technique is signature-based scanning. This involves comparing the code of a file or program against a database of known malware signatures. If a match is found, the antivirus software will flag the file as malicious and take appropriate action.
Another technique is behavior-based scanning. This involves analyzing the behavior of a file or program to determine if it is malicious. For example, if a program tries to access sensitive files or make unauthorized changes to your system, the antivirus software will flag it as suspicious and take appropriate action.
