Firstly, if I ma not in the right forum, let me know...
I have a client with an issue that I can not explain, nor can I find any information about. Here it is as he described it to me:
Client editing photos on a laptop.
Prepares to move photos to shop's desktop for sorting and in-depth editing
Expects 50GB of free space on 2TB hard drive
Opens "computer" window.
Discovers ~1TB free and growing
Files deleting actively
No "Deleting" status window
Client claims to have not accidentally deleted, confirmed by lack of status window
System was scanned last for Malware for certain on Wed 9/17/2014 by Malwarebytes anti-malware. It is currently running the free trial license and may have been scanned on startup this morning. Also running Microsoft Security Essentials. On network with a computer recently cleared of CryptoWall ransomware. No indicator that CryptoWall is remaining on network.
ZT Systems Core i7-2600 3.4GHz on Windows 7 SP1
Microsoft Security Essentials
Any ideas as to what would be causing this? If not viral, then what?
Thanks in advance for your help!
