What’s New in System Mechanic 

New Fully Integrated Product Dashboard

No more separate installs, desktop icons, or product interfaces: the free versions of Privacy Guardian and Malware Killer now open right within the System Mechanic panel.

New On-Demand Boost

The much-anticipated addition to LiveBoost is here: On-Demand Boost is the perfect complement to LiveBoost’s real-time performance boosting, by allowing you with one click to safely turn off multiple background services that drain precious system resources. Together, Real-Time Boost and On-Demand Boost deliver maximum speed, especially for specialized tasks like gaming, streaming, and more.

Enhanced ActiveCare

With the addition of an On-Demand Boost setting within ActiveCare, now you can turn off unnecessary background services automatically every time ActiveCare runs.

Enhanced Settings Menu

You can now adjust Malware Killer scan settings and Privacy Guardian tracking detection and startup behavior from within the System Mechanic Settings menu.


Enhanced Help

A single iolo Product Help now contains useful guidance through all seven major iolo products: System Mechanic, System Shield, Malware Killer, Privacy Guardian, ByePass, DriveScrubber, and Search and Recover.
