Overall, though, it's not difficult to see how the package works. All you really need to do is tap the Scan button on the sidebar and choose from the three scan types: Smart, Full and Custom. The Malware Fighter interface has plenty of panels and screens, but most do little more than turn features on or off, and can probably be left at their default settings.
That's similar to many other packages, but it only detected the most serious of threats, the kind of malware you would expect your regular antivirus to catch, anyway. This looks like IObit's equivalent of the Quick Scan in other products, where it checks running processes, the Registry, and key system areas only. On first launch the program suggested we run a Smart Scan. IObit Malware Fighter Free was easy to download and install, and, unusually, the company didn't ask us to hand over our email or any other personal details along the way.
