Conficker Worm Attack Getting Worse: Here's How to Protect Yourself

Millions of Windows computers have been infected by a new computer worm dubbed "Conficker." The situation is "not getting better," but rather is "getting worse," according to security software vendor F-Secure.

In a blog post, F-Secure security researchers report that the number of machines infected by the Downadup worm has skyrocketed from roughly 2.4 million to over 8.9 million in the last four days alone.

Downadup is a malicious worm that "uses computer or network resources to make complete copies of itself," according to F-Secure. And it may also include code or other malware that damages both a computer and network. The worm also goes by the names "Kido" and "Conflicker."
