Sorry if this doesn't necessarily belong here.
So today I went to delete files from my Dropbox root folder I didn't see necessary and for the first time I noticed one tmp-file I didn't know the source of. File's date seemed to be 11.9.2015 if I remember correctly. I ran avast scan on it just to be sure and it showed up clean (and I've ran casual scans with Avast and Malwarebytes during this month), but I deleted nonetheless, but afterwards I started to feel little uneasy about it, since I'm not familiar with what programs can create temporary files and where. I know that Dropbox has it's own chache folder for temporary files, but this file was outside of that folder.
The exact file name seemed to be "~152448641HI.tmp". I know that analyzing the certain file would be pretty impossible since it's been deleted from my computer before I checked it on Virustotal etc. but I wondered if anyone would know if the file would be one of Dropbox's own files or something else?
