Cracking the WEP encrypted connections is illegal no matter what way you look at it. What your saying is, if a store had very low security and was easy to steal from, stealing from that store but bringing back whatever you stole to make a point about how low their security is, is ethical? Maybe it is ethical, but it is still illegal. So no, do NOT crack other peoples wireless networks to leave them a "note".

I would have to recommend Microsoft Security Essentials, great anti-virus, not a resource hog and stays out of your way. Just that and a little common sense can go a long way!

if you have installed tor on your linux box, you should be able to tunnel traffic through tor using the "torify" command, example: $ torify irssi this will tunnel your irssi traffic through tor, making you anonymous. also, you will find this link useful: http://forums.remote-exploit.org/newbie-ar...y-terminal.html
