1. Whenever I TRY and visit a site on AOL, it says that there are some things missing with content advisor, YET when I check it, there aren't. This also happens with explorer, but I can get past that (it's still annoying).

2. I can't install any new AOL versions, because apparently there is a script error. I have tried multiple discs but none work, and I can't see a problem.

3. I did a 'disc cleanup' with that tool and accidently deleted my computer health FILES. Is this bad? What can I do?

4. Whenever I start up my computer, I always have to do alt+ctrl+dlt to stop 'Msinfo', otherwise my computer is really slow and laggy.

Thanks in advance.Since AOL is completely dependent on the health of Internet Explorer, I'd suggest you reinstall or upgrade your Internet Explorer to fix your AOL Problems.  You might also, uninstall your TCP/IP network - REBOOT - and reinstall your TCP/IP network and reboot.  Good luck.Anything disk cleanup deletes for you is OK to lose. Does REPAIRING IE help?more info on o/s please
