I believe the ContextPlus is a part of the Apropos spyware module and you were lucky enough to have an automatic uninstaller for it. There are a lot of people going through this issue right now and this is my post from a few other forums.
I have worked on this problem of a corrupted Device Manager, missing Network Connections, slow response times from Windows Explorer and Windows reactivation BS for about 10 hours and this has finally fixed the issue. I previously scanned the system with Spybot S&D, Lavasoft AdAware and Webroot Spy Sweeper but nothing picked up on Apropos.
To make sure that this file is available I have uploaded it to my own server and you can download it below. I also have an AproposUninstaller.exe from Symantec on there, but I did not have to try that since the AproposFix.exe worked. I am taking no credit for it, but I just want to make sure it is available to the next person that goes through this ****.
Step 1.
=====
Download one (or both) of the files to remove Apropos to your Desktop.

http://www.reesecomputing.com/downlo...ninstaller.exe
Step 2.
=====
Restart your computer and enter Safe Mode by pressing F8 on the keyboard repeatedly AFTER your BIOS loads and BEFORE Windows starts to load.
Step 3.
=====
Log into the account where the files you downloaded are on the Desktop. It should be an account with Administor privledges.
Step 4.
=====
//For AproposFix.exe:
Double click on AproposFix.exe and extract the files to your Desktop. Open that folder and double click on Run This.bat and follow the instructions. Restart the computer once you are prompted.
//For AproposUninstaller.exe:
Double click on AproposUninstaller.exe to open the removal tool. Click on the Start button when you are ready to start scanning. Follow the instructions within the removal tool.
Step 5.
=====
Once you are back in Windows running in normal mode with a working Device Manager, etc. get yourself online and download FireFox and download Microsoft AntiSpyware to help you stay protected against spyware.

You should still also use Spybot S&D and Lavasoft Adware.
