• BlackBerry® Internet Service

BlackBerry Internet Service does not have built-in antivirus software.

Spam email messages may contain computer viruses which can be harmful to your system. Always employ proper email account security measures to avoid data loss, corruption, or damage to your personal files.

As a rule, EXE files, ZIP files, or any other attachment or application sent from an unknown source should not be opened.

Email message filters can be created for the BlackBerry Internet Service account. These filters prevent unwanted email messages from being sent to a BlackBerry smartphone. These filters are not spam email message filters; they only determine which email messages are sent to the BlackBerry smartphone. Keep your antivirus software current to maximize your security.
