Microsoft, and probably most other, never send out updates
and patches by e-mail.
To update the software, you have to click a link in the
programme, or go to the related website.
This is repeated on this forum several times, and also in TV
and other media.
Some time ago a good friend of mine told me about a programme
called MailWasher.
This make it possible to see and delete all unwanted e-mails
from the server before download to your e-mailprogram.
Then it never reach your PC, and a better virus protection is
hard to find, unless turn off your PC, since most all viruses
coming via e-mail.
