An antivirus program is designed to find, detect and eliminate viruses from your computer. It’s a critical first line of defense in the battle against malware that can steal your personal data, crash your system or even track you with your webcam. Antivirus software runs in the background and continuously searches your devices for signs of threats. It also helps prevent the spread of infections through file sharing and alerts you to any issues.

Cyber antivirus is able to protect you against viruses as well like Trojans, worms, rootkits and adware. It’s important to choose the right program that protects against these kinds of threats and has a good track record of blocking them. Some programs come with extra features, such as a VPN service or password manager that will protect your privacy and devices.

Regular updates to the database of malware are another thing to keep on the lookout for. Hackers are always developing new methods to bypass antivirus protection. Make sure that your program is updated.

Certain antivirus programs include heuristic detection, which looks for patterns in how your system generally operates and can identify malicious behavior even if the virus in question isn’t well-known. Another type of technology is sandbox analysis, where you run suspicious files in an isolated environment to observe their behavior without causing harm to your system. A good antivirus program will have a minimal impact on the performance of your system. It is recommended to stay clear of software that uses a lot of resources or displays advertisements, which could slow down the speed of your PC overall.
