My relatively new Dell Inspiron laptop started performing is weird and wondrous ways today. It refused to read some thumb drives but read others without problem, then when trying the drives it wouldn't read again, it read them without problems. I tried reinserting when it wouldn't read a drive to no avail; yet when I moved to the next drive and came back to the one it wouldn't read, all was as expected. I'm also experiencing quirky response times in various apps that should not be using the Internet.
In times past when I've experienced such, I have used various tools to check for problems. My primary tools are Malwarebytes (free version) and CCleaner. I've not looked for such tools in quite some time; so I thought I'd seek advice from the cognoscenti.
What tools do you use and recommend?
