Should NIS be able to block something such as Yourexchange.com adware

Sorry if this has been asked before, but I've run a search and not found any answers.

Yourexchange.com has made IE and Google fully unusable on my desktop (due to redirecting pages and pop up windows).  While putting blocks on it as address in both this has no affect.  I've also had a quick look in Add/Remove programs and not found anything I can see as running this.

Should NIS be able to pick this up as malware/adware and block it before it redirects to a differnt address, opens pop-ups?

Thanks
