use firefox, make sure you have 'autoinstall' turned off, cookies disabled, security settings set high, that you have a firewall other than windows firewall, and that it's turned on (zonealarm will work in a pinch)
that'll stop your system from getting hacked from the hackers.
it's actually a nice setup for them. you go to their site to download illegal things, they hack your computer and steal your stuff.
*shrug*
or just go there from the school's computer, let it get hacked; and copy your .zip file to a flash drive.
