Um well I can show you how to turn off the warning but you need to solve the underlying problem. If you're getting XSS warnings on every page you visit you've got a serious problem with the machine. Given the previous problems you've had, I'd say format the thing completely and reinstall windows. When you get back up and running disable updates & uninstall IE right away & get a different browser going from the start. And delete whatever recovery partition you're using, you don't need one.
To turn off the xss warnings:
tools > internet options/properties > security tab at the top > select 'internet' as the zone > click custom level > scroll down to 'enable xss filter' and set it as disabled.
Bear in mind that if you've disabled the xss filter you're at risk to more malware infections and data theft (be it password harvesting or bank details or whatever).
