Just recently, within about 30 minutes of this post, I've been getting redirected to a Malware site which states my browser is out of date and wants me to download some crap that's obviously malware. I get redirected as soon as the page finishes loading.
It happens about 10% of the time right now while browsing this forum. I've gone to a few others sites and forums, however I've had no issue with that. This is the only site with an issue. I am using Chrome and even had the issue occur on a fresh install of Firefox (which rules out a rogue chrome extension). I haven't downloaded/installed anything new on my PC for at least a few days....and I was browsing this site earlier without any problems.
Chrome on my laptop, which runs on OSX also produces this issue...so I can rule out a virus/adware on my PC.
It looks like a possible XSS attack...perhaps it's a rouge advertisement?
