I've recently gotten into game modding, but problem is that I, sometimes, get the popup of "This folder is in use!" when trying to move a mod folder into the game directory. I have no idea what's causing it, as a second later I can click "Try again" and it'll work normally. This also doesn't happen on just new files, so I have no idea what's going on.
I haven't installed any new programs for a while, I don't think, maybe just downloaded a mod or two or something a long the lines of that. I also have KSC Free constantly running and do daily full scans, so I'm doubtful it's malware, but my paranoia says that I should still ask.
Are these ‘symptoms’ of malware, or is something legitimate in my computer ‘goofing’ and making this happen?
Forgot to mention: I've also had some "Disk Write" errors on steam that are completely random- sometimes they're there, sometimes they're not. Restarting the download makes them go away instantly.
