Upgrading Hard Drive but first Making System Perfect

Hello

I want to upgrade to a larger hard drive. I know how to do this but wanted to get some opinions first.
BEFORE I transfer over my existing hard drive's data, I was thinking I should first do a complete test(s) of any potential problems on my system first (virus, malware, etc.). Perhaps even system disgnostics, too.

Do we have here, under the umbrella of Major Geeks, a particular protocol of programs I should run that produce reports which I can submit to Mj Geeks to assess?

Thanks much for any advice.

System: Dell Inspiron 9200, Win XP SP 3
