The internet is a scary and potentially dangerous place and even here, where techies rein supreme, there be monsters.
Jesus Christ dude - don't click on any links! Are you crazy? All your bitcoin will be gone in 3 seconds. Just don't click things on the Internet - too dangerous. You should turn your computer off now! Go watch TV.
Yup, there's no point in staying under rock out of fear; like i said, just some common sense and the chance to pick up something is near to zero.
If in the unlikely case you do pick something up, having a strong encryption on wallet will still keep your bitcoins safe. The problem occurs when you dont realize that you're infected, and the built in keylogger picks up
your wallet password while you are unlocking your wallet..
