my background tab is gone and stuck with a blue screen with a warning on it from some spyware or something my brother did. I cleaned with adaware and spybot S&D, ran AVG there were no viruses, but a ton of adaware. checked hijack this all was ok. I had a program running on the task bar that kept telling my my computer was infected with viruses and spyware. found that program in winnt/system32 intel32.exe.deleted that. but I am still missing the background tab,appearance tab,web tab and the effects tab. this is a windows 2000 pro computer with sp4.
