What is Antivirus Software?
Antivirus software is a tool used to detect and prevent malware, or cyberattacks. Its purpose is to protect the user's computer from malicious files and websites. It is also known as anti-malware. Most AV programs use heuristic analysis methods, which detect unknown or altered malware strains. These methods can also help to determine the type of malware that has been infecting the computer. Some AV programs are able to monitor and clean up files that are similar to a database entry. Other AV programs use heuristic analysis techniques to prevent attacks from spreading. Most of the programs are free of cost, but you can buy a premium version to get even better protection.
The best option is to use an antivirus that is compatible with your computer's operating system. It can help keep you and your computer safe from any threats.
