3. Enable the viewing of hidden and system files and folders:


- Click the Start button, then go to Settings Control Panel

- Go to Folder Options

- In the  View tab, check the "Show hidden files and folders" option

- Uncheck the "Hide protected operating system files" option

- Click Apply and OK


4. Change permissions to access System Restore files:

- Type cmd and click OK to confirm

- In the Command Prompt window that opens next, please type in:

You are now able to open the folders used by System Restore and browse through the path C:\System Volume Information.


- Locate the infected files and delete them by selecting them and pressing Shift+Delete on the keyboard.

- Open the Command Prompt window again (first 3 steps above) and type in:


cacls "C:\System Volume Information" /P System:F
