Since yesterday I am getting repeated virus notice warnings from my anti-virus program (Kaspersky)... it tells me there is a virus coming from us.mg2.mail.yahoo.com. Mail.yahoo.com is yahoo's mail address.
I was thinking it may be a virus in one of yahoo's ads...
Since I use yahoo mail a lot I get the virus warnings all the time.

Has anyone had any false negatives when it comes to Yahoo! Mail virus scanning? I never had this trouble before.
