The dirty dozen

Antivirus software company Central Command today released its monthly listing of the top 12 viruses reported in March, with Worm/Klez.E retaining poll position for the fifth month running.

The fact that the same viruses are still infecting computers is bad news according to Central Command.

"The internet worms Klez.E and Yaha.E have remained number one and two respectively for five months. This is a clear indication that many users are still continuing to ignore the importance of installing and maintaining up-to-date antivirus software," said Steven Sendermeier, product manager at Central Command.

One new worm on the scene was Worm/Ganda, an Internet worm engineered to capitalise on the events in the Middle East. It comes in the form of an email containing pictures supposedly taken by one of the spy satellites during a mission over Iraq. Once the pictures are viewed the computer is infected.

The Top 12

1. Worm/Kelz.E - 21.6 percent of reported viruses

2. W32/Yaha.E - 10.8 percent

3. W32/Yaha.M - 8.9 percent

4. Worm/Avril.B - 6.4 percent

5. Worm/Sobig.A - 6.3 percent

6. Worm/Avril.A - 5.8 percent

7. Worm/BugBear - 4.6 percent

8. W32/Funlove - 2.3 percent

9. Worm/Yaha.L - 2.0 percent

10. Worm/Sircam.C - 1.7 percent

11. W32/Nmida - 1.4 percent

12. Worm Badtrans.B - 1.1 percent

Brother QL-820NWB Professional Label Printer

It’s easy to set up, it’s compact and quiet when printing and to top if off, the print quality is excellent. This is hands down the best printer I’ve used for printing labels.

The print quality also does not disappoint, it’s clear, bold, doesn’t smudge and the text is perfectly sized.
