Microsoft on Tuesday detailed a new vulnerability in Windows XP and Windows Server 2003 that could enable an attacker to remotely execute malicious code.
Antivirus companies discovered a fifth version of the Sasser variant this weekend, within hours of German police arresting an 18-year-old man who confessed to being the Sasser worm's author.
The latest variant of the mass-mailing Sober worm masquerades as an official Microsoft patch for the MyDoom worm.
A new version of the Sasser worm has appeared after the arrest of a teenager suspected of writing the original - but it will not be much of a threat to users who have already patched their systems.
The threat of infection by mass-mailed viruses is decreasing, according to reports, while tailored attacks are on the increase.
What appears to be yet another Microsoft security patch for the MyDoom worm is actually a computer virus. Sober.d (w32.sober.d@mm, also known as Roca.a) is the fourth member of the Sober mass-mailing virus family written in Visual Basic.
A year on, and the company's US$1 million tip-off program has nabbed just one (alleged) virus writer. Is it a bust?
Apple computers have built a solid reputation on being virus-free, but is the reality different from the image?
Learn about the plethora of security enhancements that Microsoft has included in Windows XP Service Pack 2, and how these security features could impair the functionality of some applications.
