ExpressZip and Restoring Extract All Option

You may suddenly notice "Extract All..." option is missing  in return for "Extract with Express Zip" when you right-click on a ZIP file on a Windows system. 

ExpressZip is one of products by NCH Software.  It usually comes with any NCH Software product, e.g., video or audio software.   Your system may not have any installation content or trace of ExpressZip including the registry entries.  However, there is usually a registry entry associated with "Extract with Express Zip" command, typically inside a user profile subkey of the HKEY_USERS hive.  Surprisingly the open command for "Extract with Express Zip" is set to using 7-zip command if you have 7-zip installed.

If you are using any product(s) by NCH Software, uninstalling them will usually restore "Extract All..." option but a reboot is required.  Or you may try and go to NCH Software to install ExpressZip, and then uninstall it.

Remove Alibaba PC Safe Service

If you has found the uninvited resident called Alibaba PC Safe Service under your Windows system but you cannot kick it out, the following information may assist you.  

This service is officially identified as AlibabaProtect. Alibaba PC Safe Service is just the name description.  It is typically installed in the C:\Program Files (x86) directory.   

This service appears to be inexorable.  You cannot terminate it directly through the Services application (services.msc), nor can you end it via Task Manager or the "taskkill /f" command.  It does not appear in the "Add or remove programs" section (appwiz.cpl) either.   Although there may be an uninstaller (an EXE file) under the installation folder (i.e., C:\Program Files (x86)\AlibabaProtect), this EXE always refuses to run.  There appears to be no way to stop its running, much less to remove it entirely.

This article outlines how AlibabaProtect infiltrates your system and offers a viable solution for removal without the need of third-party tools or additional software.

How or why will AlibabaProtect be installed?

Most likely your system have AliWangWang installed.  As of this writing, AliWangWang is the only online messenger for chatting with China online marketers on Taobao if you are using Taobao Web version (on a PC or laptop). 

You may be able to bypass AlibabaProtect when you first install AliWangWang.  Unfortunately, AlibabaProtect still finds its way to enter your system without your notice when you do subsequent update/upgrade AliWangWang.

With AlibabaProtect, most people will immediately notice the slowness on the system.

How to remove AlibabaProtect without additional app installed?

Before you start, you must have administrator rights to do the following.

1. Open a command prompt with admin rights
   
   
2. Type   takeown /f  "C:\Program Files (x86)\AlibabaProtect" /r /d y  
   Be sure this command runs successfully. If not, sorry you need to seek help from somewhere else.
   
   
3. Type   sc delete AlibabaProtect  
   Be sure this command runs successfully. If not, sorry you need to seek help from somewhere else.
   
   
4. Reboot your system.  If you don't want to reboot, it will be worth a try of either one option below.
   
   Option 1: End task via Task Manager to kill or stop "Alibaba PC Safe Service"
   or 
   Option 2: In a command prompt with admin rights, do the following:
   
              sc queryex AlibabaProtect  to find out the PID number, then
              taskkill /pid <pid number> /f  (e.g.,  taskkill /pid 11192 /f )
   
   If both methods fail or getting  "Access Denied" error, the only one solution is to reboot your system before going onto the next step.
   
   
5. Up to here, you should be able to remove all files and directories of AlibabaProtect
   Type    rmdir /s /q "C:\Program Files (x86)\AlibabaProtect"  in the command prompt with admin rights.
   

That's all.  Hope the above removal steps may help.  Good luck.
