How to view and get back the lost files form Pen drive affected by virus manually.

Click on "Start" -->Run --> type cmd and then run it as administrator. 

Here I assume your pendrive drive letter as E:

                                                    

In Cmd window , type as

E: 

and then press enter.

then, 

Enter this command. 

attrib -s  -h  /s  /d  *.* 

and then press enter.

Wait for the drive letter E:/ to appear again in the cmd window.

Note : Replace the letter E with your pen drive letter. 

Now check for your files. 

It will be showed in a Folder with no name or check for any newly created folders , which will have all your lost or hidden files of your virus affected pendrive .

Now copy all those files to any of your local disk .

Then format the pen drive.

And run a full virus scan...

Thank You...
