Unable to down load, combofix detected...

[spaceace7]

Hello.

After browsing the internet.. I was unable to download any files from any site using Firefox/Explorer.

I ran combofix , it deleted some files (not sure what), when it tried to reboot on its own combo fix froze up. After an hour I had to manual reboot.
Windows (XP sp2) rebooted to the "XP" splash screen and no further.
Wouldn't boot in safe mode either.

I had to boot from the original XP CD. I loaded the old cd drivers.
Once installed I loged on and restored my system from an older XP recovery file that I know was a good state.... then made a restore point...But... No internet gateway is available, my cd player was'nt recognized. It runs smoothly in that state but cant use it without internet.

I restored it to the restore point with the old drivers.. internet works BUT.. it's really slow.. delays when opening files, feels sluggish.

May still have a virus so I wanted to ask for help this time.
Is there any way to use the old back up and fix the internet issue?

Much appreciated
