Virus / spyware /trojan folders names duplicating into .exe files across network.

i have a network setup where a storing all data across a NAS server drive and all nodes running WinXP Pro SP2. there are files in all the folders of the NAS drive name copied exactly into .exe files within the folder. eg: c:\program files will contain a file called 'program files.exe' with a folder icon. this has spread across the entire network. eScan did not even detect this untill I saw these files. some are hidden some are not. on the nodes only 4 files are created in the c:\windows and the system32 directory.

how do i resolve this problem without formatting each PC.

Found something quite similar to such instance though it is not dealing with any network devices.

FYI, I try to search such instance on the more popular AV (McAfee) virus bank and seems like it is reported none found. Including eScan.  

Simply I see that some malware(s) may have infiltrated into the machines and create those mentioned scenario. Note the link depicting on the part of actually executing the "xxx.exe" where the malware will reveal even more of its hidden action.  

To confirm (with more findings), if desired, can try out
a) Have you try this already run the "xxx.exe"? If desired can try on one non-critical machine spared for test and confirmation, why not try it but please have the network (internet, lan, etc) unplugged/disconnected. Note that this machine may need to reinstalled subsequently since malware would have run something already....

b) Run the HijackThis tool ( to create a log that you can alternatively send for automated analysis in
(note: this may reveal what the machine has, if it has some sensitive s/w installed better to consider twice, not to infringe policy unintentionally)

Overall, it may not be conclusive but it does reveal more findings to confirm our suspicions ....

As for the possible resolution, a couple of tools to try out::
a) Since BitDefender mentioned to remove it,  maybe can try it.
- But if you do not to interfere or go through the hassle due to existing AV installed, maybe try a portable version (check out ClamAV, but this is purely detective.

b) Try out anti-malware removal tools (they do not need re-installation), some of them include
- Comodo BOClean (free)
- AMIR (note this is beta but free)
- malwarebytes' RegASSASSIN (free but only able to remove registry to disable it) 

- Commerical one recommended is malwarebytes' Anit-malware (

Hope it helps ...
