Today we got an suspicious mail with a download link to a bill. I downloaded the file unter an isolated linux system and checked the file with eset for linux 4.0. ESET found a trojan. After that I tested the file with virustotal, 4/56 found the trojan too. But the bad thing is, ESET for Windows, with the same singature database as the linux eset didn't found the trojan.
I must say I'm very disapounted about ESET. How could it be, that one system found the trojan and the other not.
