As long as you have MCShield set to automatically start with the boot of the Windows, it will not let the malware run (the autorun.inf file on the USB has been removed). If you want the malwre to be automatically deleted, you have to change a setting in MCShield to do so; the default is to just disinfect and shield but not to delete (in case of False Positive in the user’s mind).
The settings permissions are most likely changed by the malware. This should reset them to default values. The software has been updated so the pictures may be a little different than the new software but you should be able to make sense of what to do. If not, come back and ask questions until you are sure.
Please download “Windows Repair - All in One” from here. Please choose “Save file…” if you get options to open the file. Once the download is complete, run the file and install the program on your system. Please use the default settings for locations as it will help with log retrieval and fixing the registry should anything be needed.
Right click on the desktop shortcut for “Tweaking.com - Windows Repair” and select ‘Run as administrator’.
The program will run a self check to make sure that all the correct files are in place for it to run and then it will load the program. As you can see, there are many steps to take in using this program. Mainly, the first few steps involve checking for proper Windows files and backing up the system as a precaution.

You can read the notes on the first screen but the important thing to do is click on “ReBoot to Safe Mode” and allow the system to restart itself. Once the system is started in safe mode and you have logged in (using an administrative level account), restart the program and move onto the Step2 screen.

On this screen, uncheck All Repairs and then click (select) the following click the following: 1, 2, 3, 4, 5, 6, 8, 10, 11, 13, 15, 16, 21, 23, 26, 27, 31 and 32. The screen and options should look very much like the picture above. Click “Start Repairs” and confirm that the program starts running the fixes. This will take a while to run, so you can let it run unattended if you like. Log files are being recorded as the repairs are being executed. Once the repairs are finished, reboot your system (normal boot now) and tell me how it is running now.
