This removal tool provided by BitDefender detects and eliminates all traces of Downadup worms and probably BitDefender is the first to offer a free tool from a new domain without being blocked by the e-threat.
BitDefender has developed a tool for disinfecting all versions of Downadup viruses (also known as Conficker) and is available free for all infected users from a new domain at http://bdtools.net. If infected, this worm disables Windows Update services and blocks access to most of the anti-virus websites in order to prevent the user from disinfecting his computer. Moreover it install rogue security software on the infected machine. Downadup propagates rapidly by exploiting a critical vulnerability in Windows RPC Server and also through USB devices.
