What makes Malware Killer unique among malware removal software?

Malware Killer is unique among malware remediation software because it uses proprietary Scan Cloud™-based scanning and analysis, enabled by its own carefully developed heuristics algorithm to dramatically reduce detection time for brand new outbreaks. This method allows Malware Killer to continually add to a vast “reputation database,” and even detect previously unknown threats.


Generic malware removal tools are not adept at this. While they may employ some form of suspicious file behavior monitoring, many are clumsy and overly aggressive, removing by accident non-malicious files important to the user.


How does Malware Killer work?

Whenever Malware Killer finds suspicious samples, they are sent to the Scan Cloud Sandbox where they are safely analyzed, after which the malware detection engine is immediately made all the more powerful. Malware Killer then shares this increased detectability with all of its users, even on machines where the Scan Cloud functionality is turned off.


What is the Scan Cloud Sandbox?

The Scan Cloud Sandbox is the sequestered safe space where Malware Killer analyzes suspicious files. The results of Scan Cloud Sandbox analysis are then used to add to Malware Killer’s ever-growing reputation database. Malware Killer dispenses the updated information to all users, thereby continuously making the detection engine smarter and better able to detect very recent or even previously unknown threats.


Is Malware Killer the same as real-time AV protection?

No, Malware Killer is the perfect complement to real-time protection, as it finds and eradicates malware when all else fails. It is important to have real-time anti-malware protection such as iolo System Shield, found in both System Mechanic Pro and System Mechanic Ultimate Defense (formerly Phoenix 360). As noted above, Malware Killer is also included in System Mechanic Ultimate Defense.


What is the difference between the free and full (paid) versions of Malware Killer?

The free version of Malware Killer offers a deep inspection engine to detect viruses, spyware and many other types of malware that may have infected your PC and notifies you of the malware. 

If you purchase a full (paid) license of Malware Killer, the software will then take the results of the advanced on-demand detection and eradicate the malware from your computer.
