Short, honest answer: no. BRUTAL and its Guardian background optimizer are not meant to slow your PC down, and in normal use they don't. This page explains exactly what runs, how often, and what to do in the rare case you do see something off.
Guardian (it starts for everyone; its deep optimization engines are Pro) is plain C# code running inside the BRUTAL app itself. There is no separate Windows service, no extra scheduled task, and no PowerShell process spawned in the background. If the app isn't open, Guardian isn't running.
The schedule is light by design:
Idle CPU use is negligible and the memory footprint is modest. To learn what each Guardian cycle does, see What is Guardian.
This is uncommon, but if BRUTAL is holding high CPU or memory for a long stretch — not just a brief spike during a cycle — here's what to check:
Does Guardian add a background service that runs even when the app is closed?
No. It's part of the app, not a standalone service or scheduled task. Close the app and Guardian stops.
Will Guardian eat my RAM while I play?
It's the opposite — on Pro, while you game it trims background apps, leaving more for your game.
It feels like something is using too much CPU — what now?
Check for a stuck scan first, then report it via Contact support with your details and the Guardian log.

No. Guardian is C# code inside the BRUTAL app — not a standalone Windows service, scheduled task, or PowerShell process. If the app is closed, Guardian isn't running.
Will Guardian use up my RAM while I game?
It's the opposite. On Pro, while you game, Guardian trims the memory of background apps like Discord, Steam and Spotify, leaving more available for your game rather than consuming it.
BRUTAL feels like it's using too much CPU — what should I do?
First check for a stuck scan (disk, driver, or app-update) and cancel it. If sustained high CPU or RAM continues, report it via Contact support with your app version, Windows version, steps, and the Guardian log.
