Question : Curious Sandbox folders in server 2008

Hi All

I have a Windows Server 2008 file server where I have an external USB drive attached. In the last few weeks, a lot of folders with cryptic names have appeared in the root of this drive and every one of these folders has a folder called Sandbox inside it. There are no files in the folders and size is 0Kb.

Example folder names are

3f7d217ecc32c1744cbd039809f4e382
5f500a616f25bee45cec58ac4d65daee
6a5ec527b08c6cd12f8dd5
8bdc828c1989a47a0805731e
9d4f62bbccd412d5bccc8bb86de1
30b0d753626d47310b

Could anyone help see what they are, what created them and if they can be safely deleted. I don't have much 3rd party stuff installed on my server. Clean Windows Server.

Thanks.

Hello,

Try uploading some files within that Sandbox folder onto www.virustotal.com for a quick scan to see if they are any infections.

I also read on some Microsoft webpage that using Windows Update Standalone installer might also create those folders.
