Help - Was infected with Blaster worm. Both ISP provider and microsoft set out instructions and a patch to erradicate it. This seems to have removed the pest, however, I now find I can no longer use the SEARCH facility or the HELP AND SUPPORT ICONS via the START BUTTON.Has Worm disabled theses or is something else wrong? I am running windows Xp pro. How can I reinstall these faclilties.I would be grateful for any assistance.
