Antivirus protects computers, tablets and smartphones from viruses, spyware and other malware that can damage or steal data, corrupt programs or take control of your device. Using an antivirus program is especially important if you shop, bank or work online. The best antivirus software includes many features that help keep your devices and the personal information they contain secure.

Antivirus programs scan your computer for malicious files and programs and identify them based on detection patterns. Some programs also use sandbox analysis, which runs potential threats in a virtual environment to ensure they’re safe before allowing them on your system. Virus signatures are updated regularly, which helps antivirus programs stay ahead of current threats.

Some programs use behavior-based detection, which monitors the actions of files and programs in real time to determine whether they might be suspicious. For example, if a program tries to access sensitive data, modify system settings or connect remotely to your computer, that’s usually a sign of malware. Many antivirus programs alert you when they detect new types of malware, though some remove the threat automatically or within a set of parameters.

When choosing an antivirus program, consider its detection rate in controlled tests and how well it works with your operating system. You should also look at the cost, including any annual renewal fees, and how many devices the program can protect. Some inexpensive antivirus programs cover just one device, while midrange and premium programs offer protection for multiple platforms and often include extras like identity theft prevention.
