IT security lab AV-Test registered the 50 millionth new entry into its malware repository this morning at 5:06 GMT. The malware in question is a PDF file which exploits a security hole in Adobe Reader to infect Windows systems. It hasn't been given a name yet because it hasn't been fully identified. So far, only the heuristics of Authentium, Eset, F-Prot, Kaspersky and McAfee have issued a generic message such as: "HEUR:Exploit.Script.Generic". With other anti-virus programs, it can only be hoped that the behaviour recognition will kick in if the user does open the file.
