Possible Causes of Malwarebytes Privacy Error Code MB404104
There are a few possible causes of the Malwarebytes Privacy Error Code MB404104. One possibility is that your computer’s registry is corrupt. Another possibility is that you have a virus or malware infection on your computer. If you suspect that either of these is the case, you should scan your computer with an anti-virus or anti-malware program to see if any infections are present.
