OK, better news. I downloaded the latest release from the My Account page. When I attempted to do a standard install it stopped during the install and restarted my machine twice more with the error message that Malwarebytes could not install on my computer. I put that phrase into a Google search and discovered a forum posting that referred to the Malwarebytes Support Tool. I downloaded that and ran a repair even though pop ups were telling me Malwarebytes failed to install. It took awhile but this support tool finally got finished and invited me to install the latest release. A miracle - - it finally installed. I turned on Web protection. It has not crashed and it is performing its first system scan. When I am sure it is all working correctly, I'll provide an update. Right now it is working side-by-side with BitDefender. Next year I'll have to make a decision as to which to keep or keep both. I have been a Malwarebytes custome for a lot of years. I really wanted this to work.
