update and aquestion

First the update.  Thanks for the info on removing Norton from my crippled older computer.  I'm making headway.  After letting the older download and install updates I was finally able to restart the computer.  After the updates were installed I had webroot performanother scan.  Webroot uncovered 2 more viruses and 38 yes that's 38 separate malware thingys on the computer.  The viruses and malware are now goneI hope.
 
The question is as follows.  I keep getting a warning on my older computer that I need to repair Microsoft aps to enable other computers to send info to it.  I have no idea what to do.  I don't think the problem is on my new computer, and I don't know where to look for the problem on the older computer or the new one. Help? :)  One more question...will Webroot prevent new junk from entering the new computer from whatever weird websites my better half goes to?
 
On the BIG plus side I can't help but think how well  Webroot  is protecting my new computer and is correcting problems in the older computer.
 
Thanks again,
