Should I buy both Norton and McAfee

Greetings All:

  I have 2 computers a new one and an old one.  Right now I have McAfee installed on the new one and Norton installed on the old one, but my Norton runs out on May 25.  I make less than $15000 a year, and the expense is difficult.  I think I could by the agreement install McAfee on a second computer for no additional fee.  I get attacked by hackers alot and always have.  I think they are trying to extort extra money from me for various things online including virus support.  I think i may be able to satisfy them some by using both McAfee and Norton.  The keyboard on my new computer has already been hacked.  It even does not work all the time right now.  I must retype when the cursor spontaneously jumps to a different place in the message.  I do not use my old computer much, but I think the hackers want to extort a new computer sale out of me every year.  Because of my income I can only afford a new computer every 5 years.  I get attacked by hackers because of my past success in theoretical computer science and math that "they" want to never pay anything for, but was a great contribution to the computer field many years ago in theory of np-completeness.  Could I install both McAfee and Norton on my new computer or would this make it run too slowly?  I am not a computer expert anymore.  I gave that up long ago and I never was or wanted to be a computer security person.  I did delicate, complex algorithms.  I only bring up the past to fight back against them attacking me again for the same old reasons.
