EA Releases Fix for The Sims 4 Trojan Warning Issue on Windows

Good news for Windows players. EA has stated they are rolling out The Sims 4 Trojan fix after the latest update caused false antivirus warnings.

Earlier this week, many players reported that their antivirus software detected TS4_Launcher_x64.exe as a Trojan. In some cases, the launcher was quarantined. As a result, the game would not launch.

EA has now released a targeted update to resolve the issue, as stated on an EA forum post:

“Hi all,

A targeted Windows-only update is rolling out now to resolve the digital signature issue preventing The Sims 4 from launching.

Since this fix only updates the launcher, your game version will not change and your mods/CC will be completely unaffected.

Thank you all for your patience while we got this sorted out!”

What does The Sims 4 Trojan fix do?

The Sims 4 Trojan fix only updates the Windows launcher.

It does not change the game version. It also does not affect your save files, mods or custom content.

If your antivirus previously quarantined the launcher, you may need to repair your game through the EA App after the update has installed.

Why did antivirus software detect a Trojan?

The problem was caused by the launcher’s digital signature.

Digital signatures help Windows confirm that software comes from a trusted developer. If there is a problem with that signature, some antivirus programs can incorrectly flag the file as suspicious.

That is what happened here. The launcher was never confirmed to contain malware. Instead, the issue resulted in a false positive on some Windows systems.

Why were Mac players unaffected?

Only Windows players experienced the issue.

Windows and macOS use different methods to verify software. Because the problem involved the Windows launcher and its digital signature, Mac players did not receive the same false Trojan warning.

Are mods and custom content safe?

Yes. EA has confirmed that The Sims 4 Trojan fix only updates the launcher.

Your game version stays the same, so your mods and custom content remain untouched. Your save files are also unaffected. As always, it’s still a good idea to keep backups of important saves and content before installing updates.

If you have been waiting for an official fix before updating or repairing your game, the rollout has now begun. Depending on your region, it may take a little time before the update reaches everyone.
