Again, you don't listen, or perhaps comprehend what you read, and just want to argue. I reiterated OP's question #4, because he didn't get an answer to it that I saw in this very subpar thread, and I wanted to help him get things back on track. In particular, you have not answered it. Instead, you've wasted everyone's time by answering a different question and getting snottier and snottier with every post.
"4. I heard of people putting malware/virus on people's computer if they can have access to your laptop for just 1 minute. Saw video where if you are at a local coffeeshop and are away from your computer for just a minute, someone could plug a usb drive with malware in it and then take it out and now you have malware. Now if you lock your computer while you are not there... are you still protected from any usb malware?"
