I'll say it only one more time.
Internet IS a very dangerous place to play with, and there is no question about it. But...
Most people need Internet for one reason, or another.
If you play it safe, you can do out there whatever you want. Just stay safe.
At this very moment, I'll knock on wood, but I got connected for the first time 14 years ago, and I never had any kind (viruses, malwares, etc.) of infection.
You can't sit at your computer, and fear for your life. Just stay safe, and you'll be OK.
