A .dll file, or Dynamic-link library file, is used by a variety of different programs on your computer, and typically you do not see or tamper with .dll files. However, if you have been infected with a .dll virus you need to make sure you track it down and remove it as soon as possible. If not, the .dll virus can latch onto a different program and begin spreading harmful content through your operating system.
Press and hold the "CTRL," "ALT" and "DELETE" buttons together. This opens the Windows Task Manager window.
Select the "Processes" tab, then look through the listings until you find a program titled "wscript.exe." If you see the file click it and choose "End Process."
Click "Start" followed by "My Computer." In My Computer choose the "Tools" tab at the top of the screen, then select "Folder Options" from the pull-down menu.
Select "View" and click "Hidden files and folders," then select "OK."
Return back to "My Computer" and click the "C:" drive. Right-click and select "Open." When the new window appears look for "MS32dll.dll.vbs." If you can't find it here open the "Windows" folder and browse for the file. If you still can not find the virus push the "F3" button and click "All files and folders," then type "MS32dll.dll.vbs." This searches for the .dll virus. Once it is found you can select the file and click "Delete" to remove it from your computer.
