A new method of propagation for computer viruses is here presented, Automated File Transfer Infection (AFTI). This method is specific for the Microsoft® Windows® NT/2000/XP/Server 2003 platforms, albeit it may be extended to the 95/98/ME systems as well, and even other Operating Systems. It is based upon WinSock 2 hooking with the Service Provider Interface (SPI).(A new method of propagation for computer vi ruses is here presented. Automated File Transfer Infection (AFTI).
