RE: Spotlight Question: IE8 missing and denied permissions in Windows XP
I agree that you should check Group Policies first. If you already have MBAM (or similar) installed on the machine, run a full scan with that in Safe Mode to try to eradicate any crapware that has infected your system. If you have access to a known clean computer, you should download the Ultimate Boot CD 4 Wndows (www.ubcd4win.com) and create a bootable CD with MBAM and Avira on it at a minimum. By booting with the CD you create with this app, it doesn't matter what kind of malware is on the system since it will not execute during startup and cannot attempt to hide itself.
