It's thought to be a false positive by Google / Chome for forum signatures (like I had) on the CPU-Z / valid.canardpc.com
So I just changed it to an image.
Yep, it derped out with any thread where Glocky, 47 and Cock? had posted.
I don't think any more users have it in their sig so it should go away now until CPU-Z fix it.
