"It remains to be seen what they mean by threatening to attack us. That might mean a denial-of-service attack. We've been a target before, but they haven't tried any recently." - Mikko Hypponen, director of antivirus research for F-Secure.

Recent virus attacks contain messages that promise harm on anti-virus companies, it has been revealed. Threats have been made to antivirus companies F-Secure, Symantec, Trend Micro and McAfee. In the latest version of MyDoom (MyDoom.AE), the authors of the virus have embedded a message ridiculing rival worm Netsky and promising to attack the antivirus companies.
