After much frustration, including requests for help on Twitter, LinkedIn, etc., it finally dawned on me to do the following:
The malware message page included an option to check a box to proceed anyway, at my own risk. In no way am I recommending that you do so in a similar circumstance (this is completely up to you), however, since I have very good confidence in my security software, I took the chance. Also, the malware was being reported on a linked-to site (blog.designers-x.com), not this site.
I then looked for the offending site, found it on the Blogroll, and removed it from the Blogroll. All is working OK now - yay!
The Group Scoreboard is now also up-to-date.
Thanks for your patience - Ted
P.S. - if any of you know the owners of the designers-x site, please notify them that they have a malware problem.
