Our companies network seems to have been hit by a spambot, in other words, something is using our mail server as an SMTP relay and spoofing mail, which is clogging our mail server.
We are able to resolve the issue but it seems to reoccur.
We run Eset Nod32 Antivirus 4 and it has not been able to pickup the offending pc/server. (yes it has the latest definition). In the user manual, it says it detects and treats viruses and spyware....are spambots spyware or viruses or are they classified as its own threat? In other words, do I need a software that specialises in spybots?
I called Eset tech support and the guy was clueless, so I am hoping someone here can lend some assistance.
