Taking Dave's point that this NG gets filled with OT s**te, I'll ask anyway ...
Looking at replacing my Tosh NB200 which still happily runs XP, but is not suitable for upgrading. Current choice is a used Lenovo Thinkpad T430 running W7 Pro, 32 bit. I need 32 bit, not 64.
First thoughts are firewalls, anti virus etc. The Tosh is currently running the standard Windows firewall with Avast. Also use Spybot, Malwarebytes and CCleaner. Assuming a new (refurbished) laptop running a new 32 bit install of W7 Pro, should I make any changes?
