“Unlike last August, which spawned such high impact worms like Worm/Lovsan [MsBlaster], Worm/Sobig.F, and Worm/MiMail, August 2004 has been a quiet month in terms of new global virus outbreaks,” said Steven Sundermeier, Vice President of Products and Services at Central Command, Inc. “We’re keeping our fingers crossed that this pattern continues, however, the virus problem is more than likely going to continue to get worse before it gets better. Educating the user to safe computing practices is the key to winning the battle.”

Worm/Netsky.P remained the top virus occurrence for the month followed by Worm/Netsky.Z and Worm/Zafi.B, respectively.

Vexira Antivirus has been updated for 1653 different viruses, worms and other malicious applications during the month of August 2004.
