You are dealing with a computer guy that is either stupid or a liar.  The
cost of the computer has nothing to do with anything.  Viruses are a software
issue the "quality" of the computer is a hardware issue.
That technical guy should be selling used cars.

<< This morning, I stopped by the store where I bought my pc, to ask their
 technical guys about the virus problem.  I needn't have worried.
 Fortunately, when I got my computer, I got a quality machine that doesn't
have
 this defect.  It turns out that only computers that have a serious fault in
the
 software are capable of being infected by one of these viruses, what the
 technical boys referred to as 'junker' pc's. Apparently, the market is awash
 with them, so be warned if you are thinking of buying.

 Once again, it seems that you get what you pay for.
