There's been a lot of weird activity happening on my mac. I won't bore you with all the details but will go directly to the problem: When I open System Preferences, under Sharing, File Sharing is checked, and it says "Windows Sharing: On", "Windows users can access shared folders on this computer, and administrators all volumes at smb://176.0.195.173.client.dyn.strong-in28.reliablehosting.com"
reliblehosting.com hosts my VPN service, the server address for my VPN is xxxxx.reliablehosting.com

(I enabled file sharing a long time ago, in order to share files between my mac and an old win-xp computer, but I never intended to share files online this way.)

Last night, at 1am, somehow, my VPN was connected---I didn't know until I checked my computer the next morning, it says VPN was connected for 9.5 hrs (I worked backwards, it was 1am). I admit that my computer was turned on at 1am, but I wasn't using the VPN. I'm certain of the last part. So for some unknown reason, the VPN was connected and some strange activities was going on on my computer. I can't detect any major damage; it's mostly just minor changes---like one of the files was renamed a gibberish name.

I believe I have some reasons for concern so any help is appreciated.

Well, since you don't provide any details of the "strange activity", then no one can have an opinion or any recommendations. You also haven't specified what permissions any visitor across the VPN will have.

But it would seem obvious that, if you think the VPN has been compromised, then at a minimum you change passwords. If the problem is worse than that, somehow, you turn off file sharing at least until you have had a chance to do a forensic examination of the machine to identify what was done to it.

Okay. The activity is only mildly strange---that I've noticed anyway---mostly the volume adjusting on its own, and files being renamed. I just don't want people accusing me of doing it myself and then not remembering, so I left it unsaid. They are strange in the sense that I'm pretty sure I didn't cause them myself.
I'm always watching videos in the middle of the night, but I always turn the volume to the maximum. Maybe I disturbed the neighbours and they want me to turn it down. I really don't know. I just know that before I left the computer, the volume is at the maximum, then when I return to the computer the next morning, the volume is at only 1 or 2 bars and nobody else has access to this computer. There's also some files mysteriously being renamed.

I don't think I have valuable information on my computer that people would want to steal.

Besides, I think I should've disabled file-sharing a long time ago; it was turned on 6 months ago and then I forgot to turn it off when I wasn't using it. I really don't have any use for it now anyway.

(I don't know what permission visitor across the VPN will have. Sorry, I don't really know what that is.)
