A friend has this problem for which I can't give much support. I don't use Yahoo. >> I'm using my PC because I can't get Firefox to run on my Mac lately. I recently installed a new virus defender program on the Mac. It has quarantined a file "admin.syncdb," which I think is part of Yahoo Sync, which I had activated on my Yahoo.com account. I access Yahoo.com with Firefox on both Mac and PC. Firefox won't start on the Mac, so I can't get to Yahoo.com to disable Yahoo Sync. I can't find the offending file to remove it, and I haven't been able to find Yahoo Sync in my Applications folder. The Mac is working fine, but I'm locked out of the Internet on it until I can solve the quarantine problem. << Paul Moortgat
