Windows defender reacted to their signatures, but there was no malware in the dropbox files.
Hey @ingegnere; thanks for posting on our Community and happy Monday!
The cache folder on your computer is used by our desktop app as a staging area to download your files in small chunks when syncing takes place.
Sometimes antivirus programs will pick up these partial files as false positives and continuously quarantine them. The problem is that Dropbox keeps downloading the file in an attempt to sync the file down to your device.
In that case, you could try adding the Dropbox cache folder to an ignore list so that Dropbox can correctly sync that file and/or temporarily disabling your antivirus. Once synced, you should no longer see these warnings or quarantine messages.
