Ive got a wireless router, turned it on, mac found it, put in my details from internet provider, internet worked. Was quite easy.
There is a mac msn, u can download on msn.com, mactopia page, but i find adium much better, put adium mx in google you will find it. I found the mac msn, kept cutting off and i couldnt send or recieve files.
I have no anti virus software, not sure if u can even get viruses on macs? ^_^
For videos download, windows media player from microsoft.com for mac, on the mactopia page, and you should already have quicktime, if not get that too, then you should be able to paly most files, with those.
Hope that helps. :lol:
EDIT: Beaten to it. :lol:
