i am not able to upload screenshots here, sorry
When I was recently screening my laptop for malware and such, I accidently deleted the following file conekeyapi64.dll (see screenshot), because I got tricked by a misleading website that claimed that this file is a Trojan. I later found out that it is linked to my audio driver "Conexant". After some weeks I now sometimes get a short screenfreeze (when clicking on the YouTube video fullscreen button for example) and the audio doesn't work anymore, sometimes also the whole video gets black or green (see second screenshot). I then have to restart the browser to watch it properly again (sometimes after some troubleshooting by windows, see screenshots). I also think that the bass-quality is somehow really bad now, but that's just what I think I can't really prove it. Should I now try do download this file and somehow place it in the folder where it belongs or delete my whole audio driver and install it again?
Thanks for your help,
