Antivirus software protects against ransomware, malware, and other threats. They also protect devices from identity theft, data breaches and online fraud. The most effective antivirus software suites also include safety features like password managers, VPN and even parental controls. These suites are compatible with both desktop computers as well as mobile devices.

The majority of antivirus software utilizes a technique known as signature-based identification that has a huge database of code snippets that identify malware. During scanning the antivirus software, it looks for signatures of malware and alert users when they’re discovered. But hackers are constantly creating new viruses, with variations that can elude traditional antivirus signatures. This is referred to as polymorphic malware, and is designed to defy signature-based detection techniques. Some antivirus programs utilize cloud detection techniques to identify and block new threats.

A solution based on behavioral analysis is another feature to look out for. This is a more sophisticated approach that examines the actions of the device and looks for patterns that could be suspicious. This is particularly efficient when it is coupled with signature- or heuristics-based detection. It can be used to detect new threats, including zero-day attacks.

Businesses can also choose antivirus software that is scalable to meet their specific needs. Certain antivirus solutions are designed to operate as an entire security suite. They also include other tools like firewalls, intrusion detection systems, and multifactor authentication. Managed services providers can help business owners who lack the technical expertise required to install and maintain these cybersecurity systems.
