4.- Verify all e-mail messages received before opening them

E-mail is the most popular means of virus propagation, therefore we advise you to be particularly careful when using it.

Every e-mail message received can contain a virus, even if there is no attachment symbol accompanying it (the typical paperclip). Similarly, it is not necessary to run the attachment to become infected; on some systems, simply opening the message or viewing it through the preview pane is enough to trigger the infection.

The best way to avoid infections is to verify all unsolicited e-mail messages or those received from non-habitual sources. An indication of virus presence is text written in a foreign language in the message body..
