Yahoo isn not the problem nor the solution. The problem is whatever software that was installed and possibly Firefox. The anti-virus software needs to be setup or configured properly or completely removed. Personally, I'd remove it and try to get a refund as it is obviously defective. With regard to Firefox, it is not the only browser on the Mac, so downloading a fresh copy of Firefox would be my first suggestion. Preferences and cache files would be my next suggestion.

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 -------------- next part -------------- An HTML attachment was scrubbed...
