Hi- I use Yahoo for my email & check for my messages on
their site. Lately I've been getting bulk mail (no doubt
they are viruses) but most of them are 13K or less. There
is one there that has an attatchment. I know that with
yahoo, it lets you scan an email from their site (they
use norton) that has an attatchment. But, not all things
get scanned that have the paper clip on the message,for
exam pictures. They just open up in the same window when
you click to open the email. Which emails that come as
attatchments are the ones that get scanned. Do they have
some kind of code that tells yahoo that it will give you
that option? How can I know if its safe to open an
attatchment. (see, I have a small business and can expect
to get emails from unknown persons that get my e-address
from my business card)-I have xp,ZA,AVG,Ad-aware, and
have patched up my sp1 version.thanks
I do have
