Action

Please follow the instructions for removing PE executable viruses.

Windows NT/2000/XP

In Windows NT/2000/XP you will also need to edit the following registry entry. The removal of this entry is optional in Windows 95/98/Me. Please read the warning about editing the registry.

At the taskbar, click Start|Run. Type 'Regedit' and press Return. The registry editor opens.

Before you edit the registry, you should make a backup. On the 'Registry' menu, click 'Export Registry File'. In the 'Export range' panel, click 'All', then save your registry as Backup.

Locate the HKEY_LOCAL_MACHINE entry:

HKLM\Software\Microsoft\Windows\CurrentVersion\Run\

and remove any reference to any file you deleted.

Close the registry editor.

More Information

W32/Nofer-C is a virus which tries to email itself to addresses extracted from a variety of sources on your computer. W32/Nofer-C also infects programs already on your computer.

W32/Nofer-C copies itself into the Windows folder, using the filenames svchost.exe and kernel.dll (usually 66048 bytes). W32/Nofer-C also copies itself to a randomly-named hidden file (e.g. Uhy43cuAqUQ.exe) in your Windows folder. The virus then adds a registry entry to:

HKLM\Software\Microsoft\Windows\CurrentVersion\Run\

so that the hidden file is launched every time you logon to your computer.
