I've been pinging between 200 and 600 to optus and GA servers for the past week. No idea what it is. Tried turning off other computers on the network with no results.

Also, I've got a virus on my computer that AVG detects but does not remove=/ It's "I-Worm/Mabutu" (maybe l-Worm?). How do I get rid of it?!

Thanks for that but when I go there it says I need to install some other stuff and can only be used with Netscape:(

Try this one stick, it's a bandwidth stealing virus ><

anyone know how to get rid of w32 Jeefo virus, its something along those lines.

You could try booting in safe mode, go to the folder that has the virus and delete it manually.

Firefox = Netscape, pretty much. Either that or just load it up using IE.
