iolo technologies has sold PC tune-up software from Los Angeles since 1998, and System Mechanic is the product it is known for — a maintenance suite that cleans, defragments and tunes Windows rather than a security product in the usual sense. Its software is now published under the RealDefense group. Security arrived as an addition to that. System Mechanic Ultimate Defense is the edition that bundles protection with the tuning tools, and Malware Killer is the on-demand scanner sold within it, alongside System Shield for real-time protection, Privacy Guardian, ByePass, ioloVPN and DriveScrubber. For this index the distinction matters: what iolo sells is a maintenance suite with malware removal in it, bought by people who want a slow computer to feel faster. It is not designed or marketed as a replacement for a dedicated antivirus, and it is tested by the independent laboratories far less often than one. Vendor page →
