Computer issues

I notice a quick black screen with a cursor before the login screen and when I try to close Panda Cloud Cleaner’s processes using task manager because it would not update, it says “The operation could not be completed. Access is denied.” Panda’s permissions seem to be to lock me out of using the program as it says “Windows cannot access the specified device, path, or file. You may not have the appropriate permissions to access the item.” Can you please look through my logs and help me identify if these are malware symptoms or typical computer issues?
