I've got a Samsung Galaxy S6 Edge and today I've gotten a notification from Dropbox several times saying "Tap to add 2811fb90a1302f to your Dropbox and view it anywhere." I looked through the file system and there it was in the Downloads folder. Doesn't have any file extensions but I'm not going to try to open it to see what it is. I've tried deleting it but it keeps coming back. The only other post on this I've found is on some Norwegian site (thanks, Google Translate) posted yesterday. Has anyone else encountered this recently?
I haven't opened any suspicious emails, gone to any strange websites, or downloaded any new apps in a while. Could this be a bug? A virus? Along with the Dropbox notification my antivirus seems to be scanning it but the notification disappears as soon as I see it. I've had the antivirus scan my phone but it didn't turn up anything. Any thoughts appreciated! (viruses aside, the notification is real annoying)
