reinstalling Norton

Apologies for this...have gone through and read as much as I can.  But, northing has assisted thus far.

 

What happened was that I did something really stupid (was very annoyed after months and months about a particular matter), then, a cupla days ago, I hit a key (or two), which ended up reformatting my computer, so I lost ...Everything.

 

Have had to start all over again.  Managed at least to get I/net working, but I don't know how to get Norton back..  So, Question is, how should I go about this ?,

 

Am learning a lot, but ...Not Enough ! 

 

Would appreciate any assistance.

 

Thankyou.
