Hello, if you can use the internet in the infected computer you will have to use another computer to download files and install them on the infected one. I am Origin by the way and I will be helping you today:

Please download Ice Sword from HERE

1. Download the zip to your desktop and extract it.
   
2. Open the Ice Sword folder and then launch IceSword.exe.
   
3. Then look in the left hand bottom of the program and press "Registry"
   
4. When the registry list opens, drag the line between the two windows so you can see which registry hive you need.
   
5. Next, open the HKEY_LOCAL_MACHINE, and navigate to the following key:
   
   HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Run
   
   
6. Now look in the right side pane for two run values that are just random numbers.
   
7. Once you have found the value(s), right click it and press "Delete"
   
8. Okay the prompt and close IceSword.
