How To Enable “Show Hidden Files Option” When Disabled By a Virus

Most of us have this problem, Sometimes when virus attack our computer it disable the “Show hidden files and folders” option than even if we select the option Show hidden files and folders from the folder option window, the changes just disappear upon closing the dialog. It is because virus has attacked your registry file. So here is the solution to the problem:-

Go to Run than type regedit and click Ok.

Find the key: HKEY_LOCAL_MACHINESOFTWAREMicrosoftWindowsCurrentVersion
ExplorerAdvancedFolderHiddenSHOWALL

Look at the “CheckedValue” key. This should be a DWORD key. Check its value If the value is not 1 then make it 1.
If “CheckedValue” key is not there then Create a new key called “CheckedValue” as a DWORD (hexadecimal) with a value of 1.

Now open My Computer, on the toolbar go to Tools > Folder Option and click on the View tab.
The “Show hidden files & folders” will work properly!!!
