Mal/Conficker-A is a worm for the Windows platform.

Mal/Conficker-A can be removed with either Sophos Anti-Virus or the standalone Conficker removal tool.

Mal/Conficker-A may spread through Windows file shares protected with weak passwords (or to which a logged on domain administrator has access), by copying itself to removable storage devices and by exploiting the MS08-067 Windows Server service vulnerability.

Mal/Conficker-A will attempt to copy itself to the following location:

<System>\<random filename>
(e.g. C:\Windows\system32\zdtnx.g or C:\Windows\system32\kdcktv.dll)

This file is set up to run as a service, also using a random name, when Windows starts. Mal/Conficker-A modifies permissions on the service registry entries so that they are not visible to the user.

The registry entries added by Mal/Confiker-A are under:

HKLM\SYSTEM\CurrentControlSet\Services\<random service name>

The random service name will also be added to the list of services referenced by:

HKLM\SOFTWARE\Microsoft\Windows NT\CurrentVersion\SvcHost\netsvcs

When spreading to removable media Mal/Conficker-A attempts to create the following hidden files:

Help, my PC with Windows 10 won't shut down properly

Since upgrading to Windows 10 my computer won't shut down properly. I use the menu button shutdown and the screen goes blank, but the system does not fully shut down. The only way to get it to shut down is to hold the physical power button down till it shuts down. Any suggestions?
