Certain Microsoft applications run off Visual Basic Script (VBS) files. When a user clicks a button in Internet Explorer, for instance, a VBS file might control the action that button triggers. If a VBS file gets a virus, or if a virus script impersonates a VBS file, the application(s) that run off the file might not be able to perform the correct functions. Luckily, Microsoft includes a tool with every version of Windows that allows the user to clean these files.
Load Microsoft’s “Malicious Software Removal Tool.” Open your desktop's Start menu and click “Run.” Type “MRT” and hit your keyboard’s ENTER key. If this tool seems to be missing or broken, you will have to obtain another copy from the link in Resources.
Click “Next" and select “Full Scan.” While this takes a little longer than the “Quick Scan” default, it offers a better chance of cleaning a VBS virus script. Click “Next" and wait for the tool to finish scanning the virus-infected hard drive.
Follow the prompts that pop up to clean and remove a VBS virus script. Click “Finish" and restart your PC.
