Im on windows 7 before I start. I used this file manager for a couple of days now. Its been okay until I found out it could not open all my rar files without an error. So I tried to uninstall on the control center and I thought that was it. Until I updated Fortnite through Epic Games launcher. When I launched it, It said " Error File blocked loading" "C:\Program Files\GPSoftware\Directory Opus dopuslib.dll". I tried to ignore the problem but when I went to find a match on Fortnite it said "Client Error 0 Please Restart your client". I tried to go into cmd as admin and do sfc/scannow. That did not work. I tried bunch of other stuff. But for some reason Directory Opus is making weird files with bunch of letters and numbers. That seemed quite weird to me. Also what was weird is that there is no official uninstall for the application. Seems to me as if Directory Opus is Malware. If this is not the case please explain to me the Problem I am going through and please don't say its not directory opus causing the problem because im 100 percent sure it is.
Just run the uninstaller, then reboot at the end when prompted.
Some of the DLLs cannot always be removed until a reboot if they have been loaded into other processes. That's normal.
Opus is not malware. Please don't jump to ridiculous conclusions like that. 
If you have problems opening certain RAR files, please let us know the details and we can fix the problem, or explain why it is happening. Opus should be able to open any RAR file which WinRAR can open, since it uses the library provided by the WinRAR team.
