Learn how to resolve CPU performance issues when running the Adobe Content Synchronizer.
CoreSync.exe is the name of the installer app for Adobe Content Synchronizer. The CoreSync.exe process should not impact CPU performance when your machine is idle. Syncing folders with Creative Cloud may temporarily use some CPU resources for a few seconds. But if you see continuous high CPU usage by CoreSync.exe, it may indicate that it's not genuine. Ensure that CoreSync.exe running on your machine is genuine.
Content Synchronizer isn't genuine
If CoreSync.exe, running on your device, shows high CPU usage, it may be a malicious app that should be removed from your device:
Select the Details tab in the left panel.
Search for Creative Cloud.exe.
Right-click the process, and select End task.
Repeat steps 3 and 4 for the following processes:
- AdobeDesktopService.exe
- AdobeCEFHelper.exe
- AdobeInstaller.exe
- AdobeUpdateService.exe
- CCLibrary.exe
- CCXProcess.exe
- CoreSync.exe
- AdobeIPCBroker.exe
- AdobeNotificationClient.exe
- CreativeCloudHelper.exe
Right-click the malicious copy of Adobe Content Synchronizer and select Open file location.
Locate the root folder, right-click it, and select Delete to remove it.
Launch the Creative Cloud desktop app and wait for it to update.
Note
To prevent future malicious attacks on your computer, ensure you have installed an active and up-to-date anti-virus software.
