This, in case of penetration, will save a lot of your information.
    • Be cautious with the e-mails which contain files. The #1 pattern of fraud e-mails is the notification about prize gaining or parcel receiving. You also should keep an eye on business-related e-mails, particularly if the sender's address and the content is unknown. Bills for services and products, lawsuits, summaries, appeals and similar important files do not come without warning, and you, as a minimum, should know the sender. In all other cases it is a fraud.
