What is antivirus software?

Antivirus software, sometimes referred to as anti-malware software, is a program specifically designed to prevent, detect, and eliminate harmful software from devices such as computers and mobile devices. Malicious software, also called malware, encompasses a variety of threats, including viruses, Trojans, worms, ransomware, and spyware. Utilizing antivirus software is crucial for safeguarding your personal devices against these online threats.

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.

Types of antivirus software

There are several types of antivirus software available on the market, including:

  • 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.
  • Cloud-based antivirus software: These programs rely on the cloud to provide real-time protection against malware and other threats.

Features of antivirus software

Antivirus software typically includes a range of features to protect your computer or device from malware. Some of the key features include:

  • Real-time scanning: This feature constantly monitors your device for malware and other threats.
  • Automatic updates: Antivirus software must be updated regularly to ensure it can detect and protect against the latest threats. Most antivirus programs offer automatic updates to ensure you are always protected.
  • Firewall protection: This feature blocks unauthorized access to your computer or device.
  • Anti-spam filters: These filters block unwanted emails and spam.
  • Parental controls: These features allow parents to restrict access to certain websites and online content for their children.
