@rajas700

one thing 1st.... now trojans & virures r not the same thing....

What is the difference between viruses, worms, and Trojans?

may b the scanner of Rediffmail, that is F-Secure didnt counted that as a threath....

simply F-Secure dont have that trojan in its data base...

could be that the zip file is password protected?!

[rajas700]

No it is not password protected.

[QwertyManiac]

was the file double zipped ?
if it was so, then even ur scanner wudnt pick it...

[rajas700]

No .It is not double zipped.And i think rediff had not updated the fsecure see the copyright 2004.Now 2005 going to end.
