Forum thread being flagged as security threat

[mechascorpio]

Google Chrome is blocking at least one page of a thread in the forums with a malware warning:

Warning: Something's Not Right Here!
www.mongoosepublishing.com contains content from tnnac.net, a site known to distribute malware. Your computer might catch a virus if you visit this site.
Google has found malicious software may be installed onto your computer if you proceed. If you've visited this site in the past or you trust this site, it's possible that it has just recently been compromised by a hacker. You should not proceed, and perhaps try again tomorrow or go somewhere else....

It appears to be pages 6 and 7 of the "Prime Directive Traveller" thread, and I think that one user's avatar (user "zero") is the source of the problem because where it is being sourced from (the tnnac site).
