Firefox users targeted by rare piece of malware

Another drive-by (meaning the user gets infected just by visiting the website, no clicking or other user-initiated action is necessary to get infected) virus was detected recently targeting specifically users of Firefox.

Drive-by viruses are one of the key reasons we advocate the use of forward proxies in corporate environments to protect end-user PCs. Your forward proxy should block embedded URLs containing malware and spyware sources. If your proxy can't recogonize embedded URLs you need to strongly consider upgrading to newer technology that does as embedded URLs are the most common vector used today to spread viruses and malware via web pages.

In addition to blocking embedded URLs your proxy should also scan objects being downloaded from webpages for viruses using an effective anti-virus program. In today's malware ridden web environment, it pays to be safe.
