<p>Gibe-F and Dumaru-A threaten to strain relationship between PC users and Microsoft</p>
Sydney - November 3rd 2003</p>
<p>This is the latest in a series of monthly charts counting down the ten most frequently reported viruses and hoaxes as compiled by Sophos, a global leader in anti-virus and anti-spam protection for business.</p>
<p>For October 2003, the chart is as follows, with the most frequently occurring virus at number one:</p>
<p>1. W32/Gibe-F (Gibe variant) 22.7%
2. W32/Dumaru-A (Dumaru virus) 13.6%
3. W32/Mimail-A (Mimail worm) 12.4%
4. W32/Sobig-F (Sobig variant) 9.0%
5. W32/Klez-H (Klez variant) 4.4% 21 months in chart
6. W32/Nachi-A (Nachi worm) 4.3%
7. W32/Blaster-A (Blaster worm) 2.4%
8. Troj/CoreFloo-C (CoreFloo Trojan) 2.1% New Entry
9. W32/Bugbear-B (Bugbear variant) 1.6%
10. W32/Rox-A (Rox worm) 1.0% Re-entry
Others 26.5%</p>
<p>"This month, the numbers are telling us that we all need to think about pulling our socks up," said Paul Ducklin, Sophos's Head of Technology, Asia Pacific. "The top three viruses are exactly the same as they were last month. Two of these pose as security patches -- and we should all know by now that Microsoft don't distribute updates by email. We should all be patched against Blaster and Nachi by now, but these viruses are still at number 6 and 7. Sobig is at number 4, and this virus was supposed to stop working on 10 September 2003. PCs that are still spreading this virus have their system clock two months out of date. And Klez-H is still at number 5, despite being nearly two years old."</p>
<p>Ducklin reiterates his advice from last month:
* block all executables from email attachments to reduce your risk
* update your anti-virus regularly and frequently
* watch out for bogus emails, especially those claiming to be security</p>
<p>Sophos currently protects against 85,357 viruses.</p>
<p>The top ten hoaxes reported to Sophos during October are as follows:</p>
<p>1. Hotmail hoax 34.9%
2. Meninas da Playboy 12.1%
3. Bonsai Kitten 6.2%
4. JDBGMGR 5.0%
5. Budweiser frogs screensaver 4.4%
6. WTC Survivor 2.9%
7. Frog in a blender/Fish in a bowl 2.8%
8. Bill Gates Fortune 2.7%
9. A virtual card for you 2.6%
10. Welcome to the Matrix 0.7% New Entry
Others 25.7%</p>
<p>"A new entry into October's chart is the 'Welcome to the Matrix' hoax," said Ducklin. "The hoax is in French and warns people not to open powerpoint presentations entitled 'Welcome to the Matrix'. Rather like the most common viruses this month, this hoax threatens Microsoft's credibility with some versions claiming to come from a Microsoft security team."</p>
<p>Sophos has made available a free, constantly updated information feed for intranets and websites which means users can always find out about the latest viruses and hoaxes:</p>

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.
