This is a common problem these days that the option of “Show hidden files and folders” always gets reset each time when we set it to show the hidden files. This is sure a case of infected system either with Trojan or virus.
Possibly the system is infected by a virus named “amvo.exe”. So let’s remove this first to be on a safer side.
Steps to remove amvo.exe:
1. We need to delete following files
- amvo.exe
- amvo0.dll
- amvo1.dll
2. Open command prompt by typing cmd in the Run box. Then type
- cd windowssystem32
- attrib -s -h -r amvo*.*
- del amvo*.*
Steps to fix the problem:
- Now open registry editor and navigate to the entry HKEY_LOCAL_MACHINESOFTWAREMicrosoftWindowsCurrentVersionExplorerAdvancedFoldersHiddenSHOWALL
- On the right side see the entry named “CheckedValue”, if the value is set to ‘0? change it to ‘1?.
- The “DefaultValue” under the “CheckedValue” should be set to ‘2?.
- Click Refresh under the view tab and if the entries the same that we set just now that means the problem is solved.
