The free version of Emsisoft Anti-Malware (EAM) does not include real-time protection and is a on-demand cleaner only. If you want to increase your protection then you can purchase a license to the program in order to activate these features. Emsisoft's real-time protection consists of three components that are described by the developer themselves as:
Surf Protection: If you unintentionally try to access a website that spreads trojans or spyware, EAM will prevent you from doing so. The built-in list of known dangerous and fraudulent websites is automatically updated every hour.
File Guard: This crucial layer of protection checks all files that are downloaded or run against more than 10 million signatures of known malicious software. The EAM File Guard is intelligent and self-optimizes continually, so you won’t feel the impact of dozens of files being scanned in the background every second.
Behavior Blocker: To catch zero-day threats that aren't yet included in the signature database, EAM continually monitors the behavior of all active programs and raises an alert as soon as something suspicious occurs. Combined with the live cloud-verification of the Emsisoft Anti-Malware Network it is our ultimate weapon against specialized and sophisticated malware attacks that others can't protect you from.
