As a follow-up, it did appear that my Mozilla/Firefox was also infected with a hijacker that didn't seem evident. What was particularly weird was the fact that IE wasn't infected (go figure!). And, it specifically infected Google caches. So if I did a search on my name and then attempted to view the cache I got this:

Your search - cache:psBCkxPj6YYJ:http://www.msmittens.com/index.php?/...things-to-have!.html MsMittens - did not match any documents.
Weirdly enough, it seems to be resolved now (I'm attempting to do a deep scan using Ad-Aware and CWShredder along with a quick view of Hijackthis). It seems clean but not sure if I'm missing something... ideas anyone?
