Hi guys I downloaded some file today and did a scan with NOD32, SAS and a-squeared before opening. All of them said the file was clean, so I didn't performed my routine virustotal scan when opening unknown files. When I opened, it did nothing, just openes cmd for a fraction of a second. I uploaded the file to virustotal, and 4 scanners detected a thread. 3 of them said it was Zapchast trojan (eSafe and I don't remember wich other 2) and Avast said it was "trojano-756". So I downloaded Avast free edition, updated and scheduled a boot-scan, which deleted some files. I don't have a copy of the file, so I can't submit it to eset, but my question is the following: is this threat known to eset or is it some kind of non-functional trojan and I have nothing to worry about? I'm performing Kaspersky online scan right now, but don't hope any results, since kaspersky also said the file was clean on virustotal.
