gs.instantservice.com redirct malware?

Anyone familiar with this? Fedex tracking page starts to load and then redirects to that URL and would show “transferring data from…” forever until I closed the tab.
I left the tab open and ran full scans with avast! free and paid versions of Malwarebytes and Superantispyware - all clean. I pasted the URL into XP’s Restricted Sites and that didn’t help. Any suggestions?

if you want a computer check… attach requested logs. http://forum.avast.com/index.php?topic=53253.0

Thanks. I won’t bother with HJT logs, etc. I’m no computer “expert”, but other than minor annoyances the worst I’ve had was the Storm Worm, and how long ago was that?
