Answer 1

Duhhh  you want us to identify a "small black fast spider"....

Do you realise that there are 40462 different types of spider?

We dont even know what country you are in or where (which would help eliminate some of the 40,642 varieties of spider, and how big is small... to me a small spider has a body length of an inch or less (not including the legs).  

I would suggest that if the spider ran away from you then it has no intention of doing you any harm and obviously makes every effort to get out of your way as quickly as possible. Your only chance of getting a bite would probably be if you put your finger on it and to do that it would have to trapped on a corner or something where it couldnt escape and you cant see it. So I wouldnt worry too much and just make sure you can see where you are putting your fingers or shake any material/ clothes left in the laundry before using them or handling them much.  

Answer 2

All spiders bite !  Well, not the daddy long legs.  Don't take chances.  Did you know that the Black Widow likes dark and damp places?  There are too many kinds of spiders to know which one or ones you have.  If you are afraid, get a fogger and see if it helps.
