well fed up spent about 4 1/2 hours trying to sort this, time to ask for help me thinks
if i try and log into either ebay or google i seem to end up at some right old ropey search engines i have done all the normal stuff eg ad aware, spybot, web shredder antivirus even system restore all with the latest updates but they aint finding ought whats next all i can think of is a nice clean format
Had this problem before out of desperation i went to the homepage of the search engine and found the instructions to remove it . you will need to run "regedit" from the start menu and go to HKEY_LOCAL_MACHINE then SOFTWARE and open each menu till you find the registry entry with the name of the search engine and remove that entry
