Yahoo mail attachment download gets false positive phishing error message

This problem unfortunately is not consistent, but happens enough that it is frustrating.  Yahoo mail support simply states they can not reproduce it, and usually I cannot either.

 

When clicking on an email attachment in Yahoo Plus mail to download it, I get the download dialog box, click to open it w/Word (for example), the file downloads, Word opens, I exit back out and there is the big red X and anti-phishing message on the Yahoo mail tab.  I can "visit site anyway" and then proceed with the rest of mail items.  If I click on the exact same attachment again, it works fine. 

 

The web address found to be bad is always: us.mg4.mail.yahoo.com/dc/launch?..bunch.of.stuff.for.file.in.question.

 

System is XP Pro latest level; Norton 16.5.0.135 and all phishing updates completed; Firefox 3.0.8.

 

I do not see any way that I can log the us.mg4.mail.yahoo.com web site as "safe".

 

Any thoughts as to how I can make this problem go away?

 

Thanks.
