I cannot install the updates listed below. I have XP Home SP2 and have snoozed Avast Home v 4.7 with latest updates and turned off ZA Version 7.0.337, but it still won't let me update. I want to use IE 7 and get the other OS updates but when Windows Updates starts downloading each file, it says "Failed." I also changed the control panel to allow automatic downloads from MS and installation but no help.

Thank you!
