It's a JavaScript injection script. Looks like something is injecting code into any JavaScript your browser runs.
Probably some advertising company. The sites I can easily make out are:
To not make links:
Code: |
www.objectify.ca and chango.com
|
I'd run a virus/malware scan. If your machine comes back totally clean, it *could* be possible that it's your ISP doing the injection ... though usually they just do HTML injection to change sites ads to point at their own.
Edit:
I've updated your profile to remove it... Until you get it removed, it's going to keep coming back though.
