I believe I have found the problem. I closed my browser, and re-opened it. I got the same message again, so I made sure to copy and paste the diagnosis. This is what Google reported:

As you can see, the problem appears to be the network F1 Fanatic is hosted on – some websites that are also hosted on the same network (I’ve redacted the URLs) have been caught by Google’s security arm. as you can see, there have been 230 reported incidents from 14808 sites tested – a little over one and a half percent of sites hosted on the AS13213 (UK2NET) have been involved in the distribution of malware. I’d hazard a guess to say that any of the other 14807 sites tested by Google’s security client on this network are getting the same or similar messages.
There’s not much we can do about it for now; the diagnosis page for the blog says that the webmaster is the only one who can request a review of the page.
