Can anyone give me some insight and advice about these computer questions???

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 tasks 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?

I cant give exact answer, but i suggest you use external task manager to see more comprehensive whats runnin.

Download dTaskManager from dimio.altervista.org then run it.

You may see ALL task runnin, some maybe virus, you can decide wheter it virus or not by lookin it address, if you sure it is unnormal, you can kill the task easily ( which default task manager cant).
