I`m just a private person, but my father uses my limited knowledge about computers to fix his computer problems.
He usually kills my nerves by asking me to fix his computer, after having installed one "new" file which is making his computer even more saver, better and slower.
There are now about 40 programs in his memory, making his computer "better", so that nobody could attack his computer.
Best is, the this old guy doesn`t accept any clue from experienced persons before.
Even if you fix his behaviour, he continues adding any shit he can find in the internet.
Does anyone here know the correct definition of paranoia? :)
