My anti-virus software is McAfee. And I would like to have my incoming
e-mail
sanned for viruses. Don't you think that's a good idea?
I've been using this same program for 8 months and this problem only
started
a week ago. I seriously doubt the program is designed so that I have
to
manually change my incoming server each and every time I turn the
computer
on. That really doesn't make much sense.
Did you check if your e-mail settings were getting changed or staying
the same after you just installed McAfee AV back 8 months ago? Or did
you just notice it was changing? If McAfee (or some other e-mail
interrogating software that you installed) wants to change the server to
localhost (127.0.0.1) then why are you changing it to something else?
Obviously that software won't work unless the e-mail client send and
receives e-mail through that proxy which is running locally.
Might be McAfee. Might be something else. But something you installed
that runs as a proxy wants your e-mail program to pass the mail traffic
through it so it can interrogate that traffic. Since incoming e-mail
must obviously be written to a file on your local drive, the on-demand
scanner will catch it, or it will catch it when you decrypt the
attachment and attempt to run it. So the on-demand scanner is the real
defense. The e-mail scanning just adds another layer of scanning but it
is a duplicate effort. The e-mail interrogation can (and often does)
cause timeouts or server errors. Because the AV program must
interrogate your e-mails, it slows them getting from the mail server and
into your e-mail client (hence the possible timeout problem). If the
on-demand (or real-time) scanner cannot detect the virus in the stored
e-mail or when the file is saved or when it is opened then the e-mail
scanner won't detect it, either.
Use the e-mail scanning feature of your AV program until it causes
problems or until you can no longer stand its added delay in receiving
your e-mails, especially big ones. When it does start to cause
problems, turn off e-mail scanning. It just duplicates what the
on-demain scanner already does. Also, if you are using the freebie
McAfee suite, like those often provided by your ISP, then the e-mail
scanning is very limited in that it only scans .vbs attachments and no
other filetypes, so it is very limited value.
