Google Chrome extension for Site Advisor?

I've added SA for Google Chrome to SRWare Iron after someone recommended it to me on the SRWare forums. I have WOT as well but I thought I'd like to compare the two. It seems to be working OK. I'm also not too sure what these two radio buttons are about:

0 ~ Stop loading threat- (Redirect to SiteAdvisor)

0 ~ Continue anyway- (Icon will showup, Default)

Plus, if I visit Seekers Of Spirit with SA in Firefox it gets a Grey rating as apparently McAfee haven't come around to investigate the site yet.

Yet SA in Iron gives it a Green, instead of a Grey question mark rating. The site's fine, I just don't understand the discrepancy.

 

Stop loading = redirects you to the information site advisor has on this page (safest option), meaning you can't visit the page when malicious rated


Continue anyway = only icon shows the rating, but it allows you to navigate to the page

 

Yes, I thought it was probably something like that. I don't know how that works with WOT though. If both of them rate the page as malicious as WOT has a screen which stops you loading the page.
