Dealing with Major invfection with Marioforever and acl

hello!

The institution I work for has is under attack by a series of virus and no one know what it is or how to remove them. I would paste here a hijackthis log but we got over 5,000 infected.

All the Pc`s that the print jobs are comming from have 2 files on the registry that were installed automatically, on the same day and time. These files show on the registry as MarioForever.exe and ACL.exe.

I have tried looking for information on these files or any viruses that carry them but we have not been able to pinpoint a source. Please if anyone can help, I will appreciate it.

I am going to try and find one of the computers infected and bring you a log with hijaakthis.

Thanks!
