I heard that you can close these two ports for surfing safe on the internet. By mean don't get hacked. Now I'm closed them but I'm not sure is it really true or not. BTW, I'm on win7.
Thanks.

While I heartily recommend keeping 139 and 445 closed to internet traffic, they have nothing to do with web browsing.
These are just 2 of 65536 (2^16) ports to your system, all of which can be either open or closed. Some of them are reserved, others not, and by closing them explicitly, you might prevent useful software and services from working. To be 100% safe, in theory, you would need to isolate your machine from all networks (EDIT: that is, if we exclude other threats such as infected devices w/autorun, sneaky people, etc... :p)
