however you havve not indicated what the items ar so they could be legitimate.....
unless you post EXACT details of scan you will not get a positive response.
(WINDOWS XP SP2)
I run Spybot Ad-Aware Personal (for free) regularly, but I have just tried out the unregistered version of NoAdware (i.e. scan, but no removal, unless you pay) and it has picked out a number of HKEY items which it considers 'severe' or 'dangerous'.
My question: can/should I remove these items - all of them? If so, should I do this by disabling 'system restore' and deleting manually in safe mode, I wonder?
