The easiest step in restricting Internet access to your computer is to turn all file and print sharing off.
If you have a computer network that does share resources, turning off file and
print sharing may not be a viable option.
On your computer's desktop, right-click on theNetwork Neighborhoodicon, then left-click onProperties.
Click theFile and Print Sharingbutton.

In addition to limiting file sharing, if you use any remote access or TCP/IP software such as PCAnywhere, make sure it is adequately secured with
limited incoming users and robust password protection.
