    Plug the flashdrive into the computer. If you already have antivirus software, you should be able to right-click on the USB's icon when it loads and run the software. This should take care of removing the virus.

    How do I fix runDLL errors?
    Community Answer
    There are multiple causes for runDLL errors, such as the specific module couldn't be found. If the error is happening because some files weren't removed during uninstallation of the program, which would lead to a corrupted registry (i.e. some files are missing from the local folder), you can fix the issue by opening up the RegEdit, finding the specific module that's not found, and deleting it. You can also open up Task Scheduler, delete the entries in the Task Scheduler Library, and reboot. If some specific DLL file is missing, search the Internet for the required DLL file, and install it using the given instructions (i.e copy and paste the DLL files in C:/System32 in the folder as shown in the install instructions for the DLL file). You can find the instructions at the site you download the DLL from. You may have to reboot afterward. Otherwise, just search for the error online.
