I have noticed that there is an abundance of people who have had their files hidden/linked to an .scr file
Here are instructions for those who are having problems with missing files.
Step 1. Remove the virus that caused the problem.
Usually a good anti-virus can remove the original virus. I recommend:
avast – http://www.avast.com/index
Step 2. 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
Step 3. 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
