Hello Elise,

I have the same problem... 13 computers and a server with a Grumbot somewhere in the mix.
We ran Malwarebytes, Sophos, TDSSKiller on all machines and found nothing.

Is there a better removal tool I should try?

Thanks for your help

In case of a network infection the best solution is to isolate the terminals, reimage them and clean the server. Especially if this concerns a company network I would never assume you'd have gotten all of the infection because there is no way to tell what security vulnerabilities were exploited.

Thanks Elise, but is there any other way beside reimaging the server and terminals?
Unfortunately that is beyond my expertise and I would imagine has a considerable potential for losing data.

You'd have to analyse each terminal for infections; on a forum this is impossible (you can't start 14 different topics for 14 different computers). Have you been able to isolate infected computers (for example based on symptoms). Also important, have you checked out router DNS servers (or computer DNS servers) too see if they are set as they should and are not pointing to a malicious server.

regards, Elise
