Does anyone know what Advanced Mass Sender program is? I found it installed on my Exchange Server this morning, together with winrar and a txt file 12345.txt with about 500 emails in it. It seems to be a bulk mail program and it says something about Bank online, Chase bank. I checked around my office and nobody installed it, to you think it may be from a hacker, have you heard about this before? It is an evaluation program for 15 days. Thanks!
