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.
