We didn't notice any significant optimization, either- our second and third scans took broadly as long as our first. Custom scans took an average 5-7 minutes on our test PC, but a full system scan required 150 minutes, more than twice as long as most competitors. All scans (even just a single file) begin with an 'initializing database' step, which we found could take up to a minute. Scan times are relatively slow, at least at normal priority. The best Malware Fighter can offer is a Scan Options pane in its Settings dialog with a few useful customisations: you can choose whether to scan archives, to skip large files, to alert you to 'potentially unwanted programs', and to scan by low, normal or high priority (higher priorities improve scanning speeds but have more of an impact on system performance.) You can't create multiple custom scan types, for instance, and then tweak exactly how each of them behaves. Apart from all the marketing (messages asking you to upgrade to the commercial edition are everywhere), it's much the same as any other antivirus package. 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.
