Probleme » Cannot Find Yahoo Install

Hi to all.I have recently had my "New Tab" google page hijacked by yahoo.what i mean is i have my "on start up" page set to open chrome which is fine but any other page i open conducts a yahoo search.it has also changed my bookmarks icons to what i presume is their own choice icons eg:youtube,booking.com,amazon,gearbest,ebay etc which cannot be removed,as in there is no "X" to clear them.my internet security also showed up a program called w32 Fakedoc with some letters/numbers which i cannot find right now,and i apologise for that.i have scoured my win 7 computer trying to find where those items are hiding and if they are connected.can you please shed some light on this for me.may i add i did download 1/2 files which scanned safe.your help would be most appreciated,and thank you in advance for any help offered.EDIT:I would like to add that i have removed this yahoo from my browser settings page on three seperate occasions but it keeps re-installing.

Thank You!!!

I didn't find the right solution from the Internet.
