Upgraded my PC from 32bit windows to Windows 10 pro 64bit. I have had noting but roadblocks and errors trying to reinstall Malwarebytes. The process to reinstall MB is unreasonably slow and completed. Every time I call your customer support line I get a recording saying I'm calling outside normal business hours. At this point I'm prepared to forget about MB and look to one of your competitors to protect against malware threats. ddto contactdon'tainst malware competitors competitors User's recommendation: don't waste your time calling customer support, never get an answer.
