In outlook express I get windows security warning when opening a file
Windows found this file is probable harmful. To help protect your computer
windows has blocked access to this file.I have searched for an answer for
this and my outlook express security is the same as on a second computer
which doesn't have this problem.
You're talking about an attachment?
Starting with SP1, Outlook Express does this by default, for any file
type which *can* contain a virus. It's not a virus checker, doesn't
actually check the attachments, and this doesn't mean that there
actually is a virus there.
Such attachments *are* very risky. You often see advice not to open
attachments from people you don't know. I think that that's one of the
most dangerous pieces of advice you see around, because it implies
that it's safe to do the opposite--open attachments from friends and
relatives. But many viruses spread by sending themselves to everyone
in the infected party's address book, so attachments received from
friends are perhaps the *most* risky to open.
Even if the attachment legitimately comes from a friend, it can
contain a virus. I'm not suggesting that a friend is likely to send
you a virus on purpose, but if the friend is infected without
realizing it, any attachment he sends you is likely to also be
infected.
Personally I think what Outlook Express does is good; I never open
attachments at all, except from a *very* few trusted sources, and then
only when I'm expecting them. But if you want to remove this
safeguard, it's easy to do so: go to Tools | Options, and on the
security tab, uncheck "Do not allow attachments..."
