web browser – How can I make my extensive web surfing safe?

I often need to search the internet and open many tabs in my browser. Sometimes I just don’t have time to think if some particular site might be malicious.

I never save any pages, I merely copy some text from them.

How should I go about making this activity safe? What is the best way to make my web surfing 100% or at least 99% safe?

To sum it up:

  • I only need this solution for surfing, i.e using browsers
  • I’m on Win 7 64 bit
  • I’d prefer the simplest possible mechanics (for example, starting a virtual machine would probably be an overkill)
