A couple times earlier today, I've been routed to some MobyMax page while looking at my daily webcomics on Google Chrome. If I remember correctly, it was Penny Arcade and Camp Weedonwantcha (which I think are hosted by the same server, but could be wrong about that), but I don't remember 100%.

It looks like this is just the "we can't find your webpage" redirect, but I haven't seen that with Google before. I've just Xed out of it or hit the back button, but anyone here know if this is a legit "page not found", an indication of some malware on my computer, or an attempt to get me to install malware?

This is my work computer, so my ability to run checks on it is limited (no Spybot or Malwarebytes) and I'd rather not call IT since it happened while I was checking webcomics. Hence, I appreciate any insight.
I tried searching for MobyMax on Google, but only found info about some educational thing for kids.
