Info disappeared from flash drive

Hello evryone,

I have Sandisk Cruzer Blade 4GB flash drive, brand newone. Three days ago I plugged it and antivirus window appeared with alarm. Stating that virus detected. I haven’t paid attencion and kept searching files of my interest in PC’s hard drive. After some time I needed information to be copied and found my flash drive empty. The properties showed that files are still there (1.15GB is free from 3.72GBs). I always unplugged the drive dutyfully and securily. Still, haven’t copied or operated with it yet. Used recuva software but  it didn’t recover important Word file. Please advise how can I retrieve this file. Thanks in advance.

Probably those files are hidden. Go to tools - Folder Options - View. Make it to view hidden files and folders.
