EAHide Pro is a kind of software which is used for anti-spam on the Web. The system makes the e-mail address shown as hidden messages in the Web codes by encoding the e-mail address on the appointed Webs. While it is being browsed, the e-mail address, which can't be found out by the address searching systems, can decode automatically. In this way, the widely-sent spam can be prevented effectively. EAHide Pro can be used for personal computers (the one who need to leave his e-mail address on the message board or webs), for the Web designers, and for the Web management and protection. Version 1.5 build 1107 may include unspecified updates, enhancements, or bug fixes.
