As far as antivirus I use AVG just because its free

and its not that annoying, like others.
Also you don't need to purchase office just yet, you can get a 2010 office beta for free
http://www.microsoft.com/office/2010/en/default.aspxBeta lasts until september or august I think.
However I think you are better off asking on the computer section, they might be able to point u in the right way.
