Welcome to WebmasterWorld Guest from 188.8.131.52
I used it but am unsure what to see. Everything seems normal expect that google last visited my site on Dec 20th.
For a few domains that I just checked, the last visited information that the tool shows is much earlier than what the server logs show for googlebot visits -- it's also earlier than what Webmaster Tools says, for that matter. So I'm currently thinking that Google uses a dedicated bot to check for malware, and only that bot's visits are being reported by the Safe Browsing tool.
