Working on a MS 2003 server. Multiple files in a subdirectory all with same create/modify dates of May 2011. Suddenly, I noticed SOME of the files in this subdirectory have 0 bytes sizes and the date and times are all for the same date, July 27, 2011. This issue doesnot seem to be affiliated with specific file types as I did a scan across the server and saw this occur even with PKZIP files. The scan also showed me other files within other subdirectories with different dates. This issue seems to have started around the middle of July 2011.
Trying to research some probable causes: (a) files in my folder were not “dragged and dropped” from one location to another either (b) network admin assured me only thing that has changed (other than service pack updates) was a new backup software was implemented in July. It does do file size checking however my files that changed to 0 were last changed in May 2011. I’ve never heard of a backup software that could do that.
I also read somewhere that in 2008, there was a trojan horse Serauth1.dll that would cause this type of situation. I’ve got the admin double checking the anti-virus software to make sure this is included in the list of virus/trojans/malware to check for.
Any other ideas are greatly appreciated. Appears that every day some addtl files are being changed.
