Worm/Klez.E infections have dropped to their lowest levels since the virus first surfaced a year ago, says anti-virus software and computer security company Central Command.
In its monthly "Dirty Dozen" listing of the 12 most reported viruses, the company says Worm/Klez.G (detected as Worm/Klez.E) infections have dropped to their lowest level since its inception last April.
Steven Sundermeier, product manager of Central Command, says: "Computer users are finally beginning to understand the importance of maintaining up-to-date virus protection. This is paying off in higher dividends for them, but there is still a lot of room for improvement."
Worm/Klez.G accounted for 18.7% of all total virus infection reports for April 2003. In April last year, it accounted for an astounding 79.2%."
Two new viruses debuted in the Dirty Dozen - Worm/Lovegate.F (#5) and Worm/Ganda (#11).
Worm/Lovegate.F is a network aware Internet worm that uses many different body messages to deceive e-mail users into running it. One example is a body message stating: "Tiger Woods had two eagles Friday during his victory over Stephen Leaney. (AP Photo/Denis Poroy)."
Worm/Ganda is an Internet worm socially engineered to capitalise on interest in the events of the Middle East. One of the randomly selected body messages claimed the attachment was a screen saver containing pictures taken by one of the US spy satellites during a mission over Iraq.

1. Worm/Klez.E (includes G) 18.7%
