With Malwarebytes Ransomware Protection turned off, I am not experiencing any problems today, but am just posting this so others will no about the potential new issue with Kasperksy 2019 compatibility. I posted this same information on the Kaspersky Total Security Community web page a few minutes ago. I have used Kaspersky Total Security and Malwarebytes Premium, with exclusions set in both programs for many years without a problem until yesterday’s Kaspersky update to the (j) revision. I have been staying at Kaspersky 2019 to avoid the issues that have been reported here between the latest 2020 e version and Malwarebytes but that apparently no longer works. Upon restart, I uninstalled the new Password Manager and turned off Ransomware protection in Malwarebytes Premium 3.8.3 since I am guessing that this may be the same incompatibility problem reported on Malwarebytes Forums with KIS 20.(e). The computer would not open Task Manager or shut down normally.
As soon as the installation was finished, when I tried to save an open Word 2016 document, Word froze and would not respond.
Last night Kaspersky Total Security updated to 19.(j) and also installed a new password manager.
