Babylon search engine is an insidious pest......some describe it as malware.
It can be very difficult to remove, but as a first step try the following (with thanks to tetonbob at TechSupport Forum)
Each browser's 'Search Provider' will need to be purged of Babylon.
Firefox >Click the search engine dropdown on the upper right, select 'Manage Search Engines...' from the list.
Remove anything Babylon related.
For Chrome, click the wrench icon, select 'Tools' > 'Extensions'
Remove anything Babylon related.
Also, Tools > Options > Manage Search Engines > remove anything Babylon related.
