i did have this problem! the main problem is even if you follow all the instruction here on mozilla support on uninstalling unwated browser addons and stuff, it re-appears, and i guess you have a internet shortcut icon for iether of them on your desktop too?

these malicious programs when i had them ALWAYS re-appeared. as soon as you uninstalled it made clones to re-instal itself. there was no toehr help but to manually and VERY quickly do it.
FIRST i broguht up my start menu search app. 

next, i typed in babylon into the search to search for anything called that on my PC and clicked search, wait for the results to show now (i am on xp sp3) click on each babylon item and do shift delete this will delete each file without sending to recycle. you will need to be FAST, and also u can run uninstal too. any files that seem to be locked. that is they wont allow you to delete or such. then download (free) unlocker http://www.scanwith.com/download/Unlocker.htm CLICK ONLY THE ORGANGE LINK DIRECTLY TO THR RIGHT OF WHERE IT SAYS UNLOCKER 1.9.1

ANYTHING THAT WONT DELETE (IT WILL SAY IT IS IN USE) USE THE UNLOCKER. IT IS EASY.

the key to these types of self-cloning files (soon as u try to delete, they replicte and re-instal|) u get more. be fast and also rename some of them. which can unlock them if they let u rename them. and/or use unlocker to do so before renaming then deleting them
