I had the same issue with the person started this thread. I chose to not uninstall the Malwarebytes and then my PC crashed. I don’t know if it was crashed because there was an issue with Password Manager (there was no link to buy the Premium version and the procedure caught up in a loop), or the reason that my PC crashed was due to something else. I don’t see why should I uninstall MalwareBytes, since I have paid for the program and it is aimed at protection from malware (trojans etc.) whilst the KIS is aimed at protection from viruses. I don’t believe KIS can detect the more sneaky malware that MalwareBytes can. I remember well that in the past Kaspersky was suggesting to use MalwareBytes as a friendly site. I don’t know what has changed between them, but I find it dishonest for Kaspersky to force us remove MalwareBytes, pushing down our throats their possible problems they have had with MalwareBytes (or vice versa: MalwareBytes with Kaspersky). Either way, we all know the good old advice, to have more than one security programs scanning your system, since one might find something that the other software could not find. My 2 cents.
