Sad to say one of my file servers was exploited and used to run a Phishing scam. Have identified subject virus amongst other things.

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.

Is SE Linux enabled on your system? If this is an ext2/ext3 filesystem - look at "lsattr" and friends. fuser(1) on that file and/or monitoring it using something base on inotify(7) might reveal which process has it open or uses it.

Hope this gives you some useful direction.

Hi Can you tell me which virus scan you are using?

Thanks
