Remove Yontoo Virus - Yontoo Virus Removal Guide


‘I have a program on my computer that I did not put on.  It is listed on the title.  I understand it is a layering type device that layers web pages and builds up to a large drainage on your computer, among other things.  Can  you tell me how to get it off as I can not remove it on the Add or Remove program screens.  I think I saw it when it installed and I did not catch it as it moved to fast.  The help listed on the internet has not helped to get it off as of yet.’ – quoted from one of the victims.
