Antivirus detected malware in the Dropbox cache folder
I don't know if this is the right category. Also, I tried searching here for a solution first, but the posts were all locked.
I just started using Dropbox. I don't have many files in it. Since May 10, my virus software has found Gen:Variant.Kazy 512414 in my \.dropbox.cache. The file is ~834b6cda.tmp. The only thing I added on 5/10 is a pdf file from a trusted source. Could this be the problem? This has happened on 5/10, 5/15, 5/21 and 3 times today.
I read that the cache is automatically deleted every three days so it wouldn't be something that's staying in the cache. How should I deal with this because this has been a very easy and convenient way to share files between my i-things and my pc. Thanks.
(also, i tried using the malware and cache as tags, but it would not allow it)
Hey there Loni H. - sorry to jump in on this, my colleague Sanchez is out of office currently on a vacation leave. However, I'll be happy to help in the meantime.
In regards to what you mentioned now, kindly note that the Dropbox desktop client uses the ".dropbox.cache" folder as a staging area to download your files in small chunks during the syncing process.
Sometimes antivirus programs will pick up some of these partial files as false positives and continuously quarantine them. The problem here is that Dropbox keeps downloading the file in an attempt to sync the file down to your computer. To tackle this behavior you can either add the Dropbox cache folder to an ignore list so that Dropbox can correctly sync that file or/and as Sanchez has mentioned before me, temporarily disable your antivirus. Once synced and "Up to date", you should no longer see these warnings or quarantine messages.
Hopefully this will get you going Loni. Let me know if you need anything else in the meantime. Thank you!

Hello Sanchez
I can't deleta cache on my MacBookPro 2018, as following instructions "Go to Folder" doesn't bring me to cache folder
Can you help me with this matter ?
Thank you

After reading this, I went to Windows Defender and added an Exclude directory for my Dropbox/.dropbox.cache and everything seems to behave itself now.
