Just to rule out..have you done a hard reset of the router?
Does it occur on other sites..or just that one/ just http or https as well?
How about an encoded mac?
Edit: WOT is none too pleased with that site, so I've hashed it so people don't unwittingly click on it
Also my a/v went off with bells & whistles. If you'd truly like to rule out, just for peace of mind - I'd run thru the steps here:
»Security Cleanup FAQ
»Mandatory Steps Before Requesting Assistance
..it's easy, just copy/paste the following into your post (in order):
the contents of the MBAM log (Step 2)
the contents of OTL.txt (Step 3)
the contents of Extras.txt (Step 3)
the contents of checkup.txt (Step 4)
the contents of the ESET Online AntiVirus Scan log (Step 5)
..and start a thread in that forum: »Security Cleanup
We see redirected search results often, so better safe than sorry.
Also looks like it redirects (albeit briefly) to inq.com / »www.aboutus.org/Inq.com#redirectory-
