On Saturday, I installed required updates (they were Windows updates, I think). I restarted the computer and after that there were several problems:
1. My yahoo home page comes up but the e-mail and search engines don't work.
2. My I tunes player doesn't work; it perpetually loads, never completes loading.
3. Various podcasts don't work.
4. Weirdly, youtube does work.
5. The search engine for google works sometimes.
I checked my antivirus and it says the computer is protected.
I'm not great with computers, so any help would be appreciated. Thank-you.
