What is a GOOD website that can help me find out what drivers/applications etc.are not safe to be on

I have had to completely reinstall my operating system due to a virus...ugh. But I am pretty much updating every application and driver, however my hp pavilion dv4150us notebook (xp pro sp2)seems to have alot of processes running in the task manager and folders/files that I don't know if I need? Maybe malware/spyware/virus? I have ran my norton antivirus numerous times, but nothing...Does anyone know of a good helpful free website (not microsoft) where I can find out what these files and drivers are for so I can delete the unnessary ones? Also if i have norton systemworks premier installed on my computer should I continue to have Windows Firewall on? Oh and What does microsoft.net framework do? Do I need this? And what does the group policy setting ''NT Authority'' for? Oh...and could anyone tell me why whenever I open or try to install ANYTHING i get a popup from norton saying ''waiting ons system can of C:\....* but it has symbols and $'s in the path???
