Dorifel is a computer virus
In August of 2012, many institutions and municipalities were affected by this XDocCrypt/Dorifel virus. The virus damages Microsoft Office documents. The virus spreads through systems that are infected with the Citadel/Zeus virus, a virus that has been created to exploit bank and login data. The virus damages Office files by making them unreadable, and encrypting the original files. When someone opens an infected file, the virus can spread through existing network drives. Now the known virus scanners have been updated and the virus can be removed.
