Most antivirus software uses signature-based detection. This method creates an array of code fragments that identify malware. When it scans the antivirus software, it looks for signatures of malware. It alerts users when they are detected. Hackers are constantly creating new variants of malware that can bypass traditional antivirus signatures. This is known as polymorphic malware and is designed to defy signature-based detection techniques. To stop this, some antivirus programs employ cloud-based detection tools that make use of global intelligence to detect and stop emerging threats.
Another feature to look out for in an antivirus solution is behavior-based detection, which is a more sophisticated technique that examines a device’s behavior for patterns that could be suspicious. This is particularly effective when it is paired with heuristic-based or signature-based detection. It can be used to identify new threats, for instance zero-day attacks.
Businesses can also choose antivirus products that can be scaled to meet their needs. Some are designed to operate as a full security suite, offering additional tools like firewalls, intrusion detection systems, and multifactor authentication. Managed services providers can help entrepreneurs who do not have the technical expertise needed to establish and maintain these cybersecurity systems.
