Applian is a company that makes some fairly widely circulated media software - FLV players, RTMP stream recorders, stuff like that. They are somehow affiliated with NirSoft. Nirsoft makes forensics tools that are often mis-diagnosed as malicious software; its less clear what Applian could be doing to get the same red-flags. But red-flagged they were, by Google's malware team no less. Google's usual plan of red-flagging what appears like bad programs through their browser and search engine while not blocking downloads is a sensible way to get the word out without being overly intrusive. However, when the content that Google believes is malicious is being hosted on their own ASN, it is less clear how appropriate that is. Most system administrators are more comfortable with removing malicious software from their networks. A strange choice.
