|Hello, I actually just got done removing this from my Mother's laptop, and luckily it's a fairly easy fix. First off, "Smart Engine" is actually a malware application, not a full-fledged virus or program, that's why it's not in your "Add/Remove Programs" list. |
Here are the steps to remove the malware.
1.) Right click the "Smart Engine" icon on your desktop and select "Open file location". This will open the folder where the "virus" is located. You'll want to delete the extensions and files in that folder (one by one). The application for the virus can not be deleted because administrative permission is needed, so leave that one in the folder.
2.) After you have deleted the files and extensions in the folder, you should just have application for the virus remaining. Close that window and restart your computer. As it is restarting hold F8 and it will come up to a prompt screen. Arrow down to "Start Safe Mode with Networking" and press enter. Let your computer load and start up. Your desktop will look different and the icons will be larger, don't be alarmed it's just how safe mode is.
3.) Now you'll want to find the Smart Engine icon on your desktop (it might have moved in safe mode). Right click and select "Open file location". Now you should be able to delete the virus application that you left in the folder. After you delete the application, you'll want to delete the folder itself. There should be a dialog to the left of the window and the folder should be highlighted or selected. Right click and delete.
4.) Once you have deleted the application and the folder, delete the "Smart Engine" icon on your desktop and then you can empty your recycling bin to finally remove all traces of the malware. Restart your computer and you'll be set.
