What is Antivirus Software?
Antivirus software protects computer operating systems, programs, and files from malicious software such as malware, ransomware, spyware, and adware. Once installed, most antivirus software runs automatically in the background to scan, detect, delete, and block cyber threats. All of the best antivirus programs scan every file in real-time to ensure malicious software never starts running on your device.
How does antivirus software work?
It’s very Antivirus software scans incoming files against an extensive database of already known viruses and malware. Typically, most programs will use three different scanning detections: specific detection, generic detection, and heuristic detection. Specific detection identifies known malware. Generic detection looks for malware variants with a common codebase. Heuristic detection scans for unknown viruses to identify suspicious behavior and file structures. When the program finds a file that matches a virus from the database, it is isolated and removed from the computer network.
How much does antivirus software cost?
The pricing of antivirus software depends on several factors, such as the subscription length, type of features, and the number of devices covered. Paid versions typically offer additional features for password management, parental controls, and VPN—to name a few. The industry standard is a one-year subscription for up to three devices, ranging from $20 to over $100 per year for personal plans. Corporate plan pricing typically requires you to request a quote.
