Happili infection in Chrome

I seem to have picked up the Happili infection, so far it doesn't seem to be affecting Explorer or Firefox but does redirect Google searches in Chrome. In addition "happili" is now pinned to the Chrome menu in Programs. Once I experienced a computer slowdown but it seems to be operating at normal speed now.  

 

I have read the "fixed thread" on the forums, should I run and post the aswMBR and OTL scans? I have run the full Norton scan without any results.

 

I am running Windows 7 x64, Windows and the browsers are up to date with patches. Is there a source of information on how happili is spread? We don't any exotic websites or downloads, and any thumb drives do get scanned by Norton.

 

Many thanks,

Don Williams
