Conficker has been around for a while, but recently this worm has become really widely spread, thus increasing the probability of being infected.
Fortunately many antivirus developers have been working on specific tools to fight against Conficker – also known as Downadup or Kido - and all its variants. This is the case with Symantec and its Symantec W32.Downadup Removal Tool, a simple yet very efficient tool that analyzes your system and enables you to get rid of this well-known worm.
Symantec W32.Downadup Removal Tool doesn't require installation, though you need to have admin rights to run it. The program works on its own and doesn't need any configuration or user intervention. After the scan is done, the program creates a log file.
Symantec W32.Downadup Removal Tool helps you scan your system for the Conficker worm and erase it if necessary.
