Strange number sequence

I have just started getting a strange number sequence on the screen when opening
Internet Explorer 10.
It looks like this:

Ref A: bfbc89cad7c2449eaec551cca4e0e0cb Ref B: F7F4AA30D081DB7BAEAA23C659BDFC30 Ref C: Sun Jul 14 09:37:43 2013 PST

I have no idea what this is or why I'm getting it.

Any ideas?
