[CentOS] CleanLog.h

Sad to say one of my file servers was exploited and used to run a Phishing scam. Have identified subject virus amongst other things. It appears twice in a virus scan; /sbin/z (which I assume can just be deleted) and /sys/bus/serio/drivers/atkbd/description. The latter file is also present in identical uninfected machines. I have been unable to open the file, even with root privileges, although it appears to be a text file. Any suggestions on how to proceed appreciated. Guess I could delete it and copy over the file from an identical machine.

Thanks in advance, B.J.
