Thanks to everyone that replied to my questions(even if they did seem odd to you)
Iv'e actually come to the conclusion,that the best solution for (me)would be to not use a computer that is connected to the net at all to do work on.

Iv'e actually done some research on "Hacking" since my original post,which has basiclly opened my eyes..to how easy hacking actually is.

Anyone with good experience with comps/hardware,(a good background in programming also helps),especially in the windows enviroment,wouldn't find it too difficult.

From what iv'e read.there is this Glam/moral/ethics rubbish,about hacking,and Big ego's,amongst hackers(which actually made me smile)
As from what i have researched,a 12 year old kid could be a hacker LOl.

What amuses me most,is these guys think they are some kind of 'elite'.
when most of them,i would simply refer to them as 'scripter' kiddies.
i could show them code,that would 'scare' the life out of them

Its a very interesting subject(anti- hacking)and something i am quite interested in,and maybe in the future(when i have more time)might look into taking part in.

But for now,i hardly have time for any hobby projects.

Anyhow,thanks again for your replies.
