Thank you for retrieving my Thunderbird email and all the old files. My PC is running but periodically locks up, The CPU usage is often it 100% usage due almost entirely to the antivirus program Malwarebytes. I have two questions. 1. Can I pause Malwarebytes and run it say, once weekly or on demand? I have attempted this but I haven't succeeded. 2. If this is not possible I would like to cancel my subscription and have a refund. I don't feel the need to upgrade this computer, it is less than three years old, and is not used for any intensive apps, such as gaming, mainly MS office 2000 pro and Photoshop. Peter Sayers
