programs question...
 

hey just 2 quick questions:

1. Norton brings out a new version of its antivirus and firewall each year... but is there any real point in buying the new version each year? or can you stick with one for a couple of years and just maintain the definition updates?

2. i heard a while ago there is a free program for viewing docs... but im not sure what it is called... i need something for viewing docs, but i dont want to have to go out and pay for the whole office pack... what do you ppl use?
