Spotbot and Adaware did it.
From what I can gather the company above is owned by a parking company. Reading around it seems that they're using Adwords, not Adsense (contextual) and there are accusations of fraud.
Beats me how Google squares the circle of paying out money to them if that's the case.
Update: didn't work. Started getting those parked pages again. Have now uninstalled IE8, is working so far

For anyone interested, I finally solved the searchportal.information.com problem by going to the MS site and searching for reinstallation of IE. After downloading it removed the original, removed associated malware and reinstalled.
I dislike IE as much as anyone, but I need it for site testing :-)
