Hi all,
We had an outage on the server that maintains the list of malicious URL's as defined by the Google Safe Browsing list. The outage started slightly less than 4 hours ago. The server was brought back up 30 minutes ago. So this may have caused the symptoms you're describing above.
Please do another scan and let me know if it's working now.
Regarding the high load message. This has been ongoing for about a week and should be resolved shortly.
Regards,
Mark.
