Protect your computer from DHAs
A directory harvest attack is an action that involves seeking the valid e-mail addresses that are connected to an e-mail server and adding them to a spam database. Harvesting e-mail addresses can be done either by sending messages to different possible user-names which are generated by randomly combining letters and numbers. Another method is sending messages to likely user-names like initials followed by common surnames. If the e-mail account is invalid, the server will reply “not found”. However if a valid e-mail account receives the message, the message doesn’t return thus the DHA program retains the e-mail address for future spamming. Spam filters are internet applications that could counteract this; consider downloading them into your computer.
