File Type Transfer Screening - IM-Worm Protection for Yahoo Messenger
In addition YTK Pro blocks the transfer of potentially malicious files via Yahoo! Messenger's file transfer using a technology we call FTTS or File Transfer Type Screening.This unique technology analyses the type type and blocks those which it deems to be potentially harmful. By default, Windows still hides the extensions of potentially harmful file types like '.exe' leaving you open to the 'double file extension' exploit. This exploit could allow a user to send you a file called mypic.jpg.exe but would only appear on your windows pc as mypic.jpg. Because Windows has hidden the '.exe' part it appears to be a harmless image file. However... it is more than likely malware masquerading as an image file.
