I noticed an issue today when my computer couldn't play sound. The Windows Audio Service is turned off and refuses to turn on. When attempting to turn it on using Admin Command Prompt I received an "Error 5: access is denied" message. I recently installed Bitdefender (which can't detect any problems) so wondered whether there was a conflict, but want to scan for malware further before disabling it.
However, after downloading Malwarebytes, it is unable to install and I receive an error message. I downloaded and used the Malwarebytes Support Tool to clean any past versions that I may have forgotten about but, after cleaning, the installation still fails.
Please can you help with this?
