Oh great! This stupid computer froze again! That's the third time today! Hey Samuel, can you come take a look at my PC? It's acting again. It must have a virus or something.
I ran a virus scan on your computer, and it turns out that you have a lot of infected files!
But I'm quite careful when I'm browsing the internet, I have no idea how I could have picked a virus.
Well, you have to make sure that your anti-virus software is updated regularly. yours wasn't up to date, that's probably what was causing your problems.
Ok. Anything else?
Yeah, try not to kick or hit the computer!
