|Missing files on a disk that have been hidden by a virus.|
I have noticed that there is an abundance of people who have had their files hidden/linked to an .scr file
for those who are having problems with missing files.
First: remove the virus that caused the problem.
Usually a good anti-virus can remove the origional virus. I recommend:
avast - http://www.avast.com/index
second: scan the system with a malware removal tool
malwarebytes - http://www.malwarebytes.org/
(both of these have a free version, that is the why i recommend them)
make sure that these scan your pen/usb drive as well
Third: find your lost files
For example, go to command prompt (CMD) on your computer and run the following DOS command. Here we assume that the drive is G: drive. If its not G: then replace G with correct letter as applicable.
ATTRIB -H -R -S /S /D G:\*.*
This will show all files on the drive in question, so your data is back at least.
