Sims 4 Mod Fixer runs a set of pre-launch safety checks automatically during a normal scan. The analysis happens on your computer, there is no account, and mods you disable are quarantined rather than deleted. Here is what each flag means.
We publish the severity rubric on purpose: a flag should be something you can read and check. Nothing here is a verdict on a creator.
The three flag levels
Every safety finding falls into one of three levels. The first two are about awareness and review — they are never an accusation. Only the third level uses words like “threat,” and only when the evidence is a documented, verified sample.
| Level | What it means | What you should do |
|---|---|---|
| Capability note (info) | A script uses a capability — such as network access — that many legitimate mods also use (built-in update checkers are a common example). No action needed — this is here for awareness. | Nothing. Informational only. |
| Flagged for review (orange) | The script shows signs of unsafe or unexpected behavior, or it could not be fully inspected. Many legitimate mods never look like this. | Verify this is the official release from the creator's page before trusting it. Disabling is optional and fully reversible. |
| Known threat (red) | The file matches a known threat, or an executable file (.exe, .bat, .dll and similar) is sitting loose in your Mods folder or hidden inside a script mod's archive — Sims 4 mods never need executable files. | Treat as unsafe. You can still restore it from the app if you believe it is a mistake. |
Script safety checks
Sims 4 Mod Fixer checks script mods for signs of unsafe or unexpected behavior and flags files that need your attention. It also warns you when a script cannot be fully inspected. Nothing is automatically deleted.
What does "flagged for review" mean?
Flagged for review is an orange awareness level, never an accusation. It means the script shows signs of unsafe or unexpected behavior, or it could not be fully inspected. Many legitimate mods never look like this, so it's a prompt to verify the file is the official release from the creator's page before trusting it. Disabling is optional and fully reversible.
How the safety checks work
- It runs before you launch the game. The app scans files in your Mods folder. It does not monitor the game while it is running.
- It checks files against known threats and flags executable files that do not belong in a Mods folder.
- Everything runs on your computer. Your mod files are never uploaded for analysis.
How to review a flag
A flag from Sims 4 Mod Fixer is not proof that a mod is broken or malicious. Some results may need review when one mod depends on another. The safety checks are the pre-launch checks described above. Read the evidence the app shows and check the creator's page before removing anything.
Our safety promise
Every safety feature follows the same doctrine the rest of the app does:
- Mods you disable are quarantined, not deleted. They are moved aside into a vault and can normally be restored from the app. The exceptions are listed plainly.
- Every flag is reviewable. You see the evidence behind each finding and decide for yourself.
- Disabling is optional and reversible. A quarantined file can normally be restored to its original spot from the Quarantine page. Restoring a file will not overwrite an existing file in your Mods folder.
- The checks happen on your own machine. No account, and your mod files are never uploaded for analysis.
