How to Remove a Virus on a DLL File

1. Run Microsoft's Malicious Software Removal Tool. To do so, open your computer's Start menu and click on the dialogue titled 'Run.' Type 'MRT' when the Run dialogue opens and hit the 'Enter' key. This application comes pre-installed on Windows 7, Windows Vista, Windows XP, Windows 2000 and Windows Server 2003. If the repair tool is missing or broken for whatever reason, download a new copy from the link in Resources.
2. Click on the 'Next' button.
3. Select the option labeled 'Full Scan.' While this takes a bit longer than the 'Quick Scan' default, it offers a better chance of removing a DLL virus.
4. Click on the 'Next' button. Wait for the tool to finish scanning your DLL files to find the virus.
5. Follow the prompts that appear to remove the virus on the DLL file.
6. Click on the button labeled 'Finish.'
7. Restart your PC.
