First off, wait for an official response from anyone before you start drawing conclusions. Panicking never helps anything. Stay calm, this is something I'm already working on fixing. Yes, this is on the forums end. No, you don't have malware. The site you're redirected from by Google might try to get you to install or buy something, but relax for now. Don't click any links on that page and you'll be fine. Just click back if you're landed there by Google searching.
Yes this is something I was made aware of and am looking into it. It wasn't really "hacked" as there was just some code injected into a theme file somewhere by a drive by bot and I just need to figure out where it is. The problem is the code is encrypted so it's a huge mega pain in the ass to find and get rid of and I've already started looking into it when I had to crash out last night. I'm in the process of moving as well so I've been pretty busy. Rest assured I'm looking into it and as long as you're not clicking any links on that site you should be okay.
Basically, this is a more modern version of a problem that's been around awhile. Which also means where injected code is in how-to-remove articles, isn't where it is on our end. Which means I'll have to dig up wireshark and find all that crap out myself. I literally just woke up and have coffee brewing and will tackle it though
I wish to make note that this is a *minor* albeit, annoying problem. It will be taken care of though!
I'll post an update once I have it taken care of.
For now, stop using Google to search for forum topics and use the forums built in search function.
