herdProtect is an anti-malware scanner and remover that uses cloud-based scanning to detect malware on your computer. It provides real-time protection against malicious threats, including viruses, spyware, adware, and rootkits. herdProtect uses a multi-engine approach to scan your computer, including both signature-based detection and heuristics to identify and remove malicious software. It also provides a layer of protection against zero-day threats and other unknown malicious threats. Additionally, herdProtect gives you the option to scan your system in either automatic or manual mode, allowing you to customize your protection according to your needs.
If I remember correctly, Reason Core also has many different antivirus engines.
