Help for old newbie

I have downloaded Blender and some tutorials to get me started,but when I first start Blender I get the following warning,which,as a computer illiterate I cannot understand:

import site failed; use -v for trackback sys_init:warning- no sitedir added from site module.
I would greatly appreciate it if someone could explain this message and what I should do about it in simple language please.
regards Bob. :o

At the top of this page there is an orange bar. On the right of that bar there is a link labelled search. Click on it.
In the box presented type import site, turn on Search for all terms and click Search.
Sift through one of the many times this has been asked before, and read the answer.

If you can’t be bothered to do all that, then just read
