These days I have problems with trojans in attachments like:
- //EZuS.zip//invoice_scan_xcFSuO.xls.js contains a potentially infected object HEUR:Trojan-Downloader.Script.Generic.
- //TuxX.zip//invoice_YAFFOg.doc.js contains a potentially infected object HEUR:Trojan-Downloader.Script.Generic.
I have a relay to my in-house server. Relay with postfix + amavis + spam assassin + clamav.
We need to send and receive .js files. So i only want to block the .doc*.js and .xls*.js
Which is the most efficient way to block this kind of spam?
