To uninstall YAC I had to do a number of things. I used Revo Uninstaller Pro.- the trial version. Had to use it 9 times. When you go to the main page on Revo hit the "Forced Uninstall ( the red X). Under "Program's Exact name" type YAC. Next browse for the Full Path. Browse for "FOLDER", then under COMPUTER hit LOCAL C. Go down to PROGRAM FILES (X86). YAC should be there. Uninstall all. Do the uninstall over and over again till can't find any trace. Also delete the "Log YaCy". Next go to Control panel and under Internet Properties and if YAC is your home web page delete it and put another page name. Finally on this page use the Microsoft Fix page to delete {B6900F29-8805-4CE8-8046-25093CD4F32C}. After doing all this I finally got rid, so far, of YAC.
