Hello and welcome to Tom's Hardware Forums.
Reboot into Normal Mode and press your Control, Shift and Escape keys together to bring up the Task manager. From the Process tab>File>New Process menu, type
explorer.exe and press Enter. The task bar should then show up and we can start dealing with the other problems.
Can you please then go back into MalwareBytes, click on the Logs tab and copy and paste the log back here?
