Hello, I just came back from the TV, and saw this warning: The alert window screenshot The program "infected", is Trillian, and is used as an IM like (or instead of) MSN Messenger. I am 99.9% sure that Trillian is not infected by any virus, trojan or what-so-ever... When my friend had sent a message to me, this warning popped up. Telling me the e-mail adress of my friend was infected by "POLY.CRYPT.COM", which it also said was "a probably unknown virus". I have searched around for it on the net, but found nothing, except ONE post on this forum, telling me nothing. Does anyone even have any small clue of what it is, or can be? I may also say that the directory (D:\Program\Trillian\users\default\cache) does NOT exist, not even in the registry. And the file "firstname.lastname@example.org" is the e-mail adress of my friend... And not a file with the type ".com"... Just a plain file with no extension. (If it had been a file, ofc ) The interesting thing with this, is that I can see a connection between "POLY.CRYPT.COM" and MSN (and hotmail), do you? Read the other post, and you will understand why... https://www.wilderssecurity.com/showthread.php?t=115005 There they have the same problem, but with IMON instead of AMON, when they log off from hotmail! Anyways, I gotta go now... I hope you can help me, Thanks in advance /Patrik PS. Can this be some odd "protection" by Microsoft? I heard that they are afraid of hacks of IMs that would take over Windows, or something like that... Just a false rumor?
