Le site balconycontainergardening.com est-il sûr ?

I was attacked, about 30 seconds after choosing the site from Google search results (neither Avast nor Chrome nor WOT had any rating, good or bad), by a popup resembling those malware popups that tell you your computer is harmful/dangerous and giving you a number by which you should contact Microsoft...along with the popup window, a klaxxon alarmed very stridently and, without carefully reading the popup itself (it seemed to report that Chrome was telling me my computer was in danger), I swiftly closed the page. I don't know whether this was an example of phishing or malware or a virus. The popup's behavior was nearly identical to a very pernicious virus/malware infestation I incurred last year. I'm running AV and malware scans.
