Where is it coming from?.....

[Mygreenihc]

I am battling two trojans that keeps showing up called Trojan.Agent and Backdoor.IRCbot. They are easy enough to get rid of, but within an hour or so, they are back. Corporately, we use a big name antivirus package including thier malware scanner. I do no like to bad mouth anyone, but this package does not even see these trojans.

I have a network of about 300 PC's and every time I clean it from a PC, it comes back. Does anyone know of any way to scan across a network to try and figure out where this is coming from?

Adding to that, if you don't have a corporate license for those computers, you are violating Malwarebytes' license agreement. The free version is only for home or personal use.

You would need to use a network packet sniffer to determine who has it and where it's coming from. Original point of origin may never be known.

As mentioned though you really need to license the product to use in a Corporate environment.

We can help assist you with removal but you'd need to contact Malwarebytes Support <support@malwarebytes.org> about licensing and support.

Thanks.
