To avoid any sort of browser "infection", you could try curl for Windows. It's built in on most UNIX/linux OSes and very easy to use. E.g., from the command prompt:

curl http://www.somesite.com/stuff.html -o somesite-stuff.html

This would download the stuff.html file from somesite.com and save it locally as somesite-stuff.html.

Since it's a command-line utility, you could batch a bunch of sites together.
