Puzzlebrains

If you visit the puzzlebrains.com website, you may find an alarming message telling you that the site may contain malware that is trying to steal your passwords.
I am trying to find out exactly what has caused this, since I am currently unaware of any such problems with the site.
Hopefully this will be resolved shortly.

UPDATE: OK, so there is no actual problem with the website, so there's no need for anyone to panic; it's merely Google being overcautious because our site doesn't have a formal security certificate. This is in the process of being resolved. However, the message is likely to persist for several more days at least.

UPDATE 2: Everything should be OK now. If you get a similar message in the future, please send me a PM!
