 Special detection  SPR/ASF.GetCodec.Gen

SPR/ASF.GetCodec.Gen is a detection for multimedia files that contain a special command to download new codecs. Normally, codecs are required to play video or audio formats. This mechanism got hijacked by malware, which simply downloads Trojans instead of a real new codec.
