News.com reports that Symantec and Yahoo will be announcing a "new security offering" sometime today. News.com says this partnership will "improve online security for consumers." But honestly, I have no more details. Is it email focused? Web search focused? Is it desktop focused? We don't know as of yet. So stay tuned.
Postscript: BetaNews has more details in Yahoo, Symantec Partner on Net Security, explaining this is allowing several Yahoo online properties such as Yahoo Mail to use Symnantec security products for 30 days free, followed by a 12 month subscription offer.
