this infection seems to be accompanied by a MBR rootkit. Please restore your MBR as described here, using the Recovery console. I've noticed that the system CD may not be available for some of you. In such case, please check whether the Recovery console is not installed on your system by vendor as described in this MS article (How to install the Recovery Console, step 5) and use that avenue. Alternatively, you may be able to install the Recovery console as described here (method 3).
Restoring the MBR using the MBR fix utility as described in the above linked article may not be able to rectify the situation, but it's worth the try in case the recovery console is not available.
Please let us know results (kindly include most recent GMER scan results in case the issue persists after rebuilding your MBR).
