Antivirus solutions protect against ransomware, malware and other threats. They also protect your devices from cyber-crime and data breaches. The most effective antivirus software suites come with additional security features like the use of a VPN as well as password manager and parental controls. They’re compatible with desktop computers as well as mobile devices.

Most antivirus software utilizes signature-based detection. This method keeps an array of code fragments that identify malware. During scanning the program, antivirus programs scan for these malware signatures and notify users if they’re found. Hackers are constantly creating new variants of malware that can bypass traditional antivirus signatures. This is referred to as polymorphic malware, and it’s designed to defeat signature-based detection techniques. To counter this, certain antivirus programs use cloud-based detection tools that make use of global intelligence to identify and stop new threats.

A solution based on behavior is another option to keep an eye on. This is a more advanced method that analyzes the device’s actions and looks for suspicious patterns. This is especially effective when combined with signature or heuristic-based detection. It can be used to detect new threats, including zero-day attacks.

Businesses can also choose antivirus programs that can be adapted to their needs. Some are designed to be operated as a full security suite, providing additional tools such as firewalls, intrusion detection systems, and multifactor authentication. Many business owners don’t have the technical expertise to set up and manage these security systems, so they can turn to managed services providers for help.
