iolo System Mechanic Professional

System Mechanic Pro is iolo's Windows PC cleanup and optimisation software that includes real-time antivirus and malware protection. A computer virus is a type of PC software that can infect a computer system and when executed, replicates itself by changing other computer programs and inserting its own code into those programs. System Mechanic Pro quarantines suspicious files and prevents them from spreading across your device. You may enable automatic renewal during checkout and update your automatic renewal preferences by logging into your iolo Account. It runs on Windows.

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 →
