Few days back I got this newfolder.exe (a hidden folder) virus, also known as Sohanad W32.HLLW.Ssdx in my Mp3 player may be while transferring data from a college’s computer.And then through Mp3 player to my laptop and it automatically disabled Task Manager, Registry Editor, Folder Options, Run in start menu.

To remove this I had to format my computer and Mp3player.But last night I got the same virus and this time I searched through Google to remove this and came across an excellent removal tool by Tech Updates which removes this virus in safe mode without formatting.The download links are available at end of the post.
There is also one alternative to fix this virus given on that site:

Delete File named svichossst.exe

[HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Policies\System]
“@”=[HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Run]
“Yahoo Messengger”=

[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon]
“Shell”=”Explorer.exe “
