use kaspersky anti virus 7 (KAV7) for it.

There are lot of BRONTOK a worm virus you can find here - how to remove them and obtain specific anti-spam software that can wipe BRONTOK off automatically for you if you can afford paying yearly subscription renewal every year. Those anti-spam software is completely different than freeware anti-spam software for those who cannot afford yearly renewal.
