I just read a scary article by a security firm in Europe that malware is
being delivered by browsers hooking into site like Yahoo and Fox. For the
malware to be installed all that is needed is to connect to the page with the
ad.

Is there anything to this? If so what is the defense?

1) Make sure that the Operating System is kept up to date.

2) Make sure that *every* installed program and application is kept up
to date.

3) Use a Limited User Account (XP) or Standard User Account (Vista/Win7)
for day to day use. Log in to a User Account with Administrator
privileges when installing software, hardware, or changing system's
settings.

4) Use a router that includes a hardware firewall that is NAT enabled.
Most wireless routers have this feature. In combination with a hardware
firewall, the native Windows firewall provides sufficient protection. No
3rd party firewall will be needed.

5) Use a web browser that can block *all* scripts on websites until
*you* can inspect them.
Use IE 8's InPrivate option with InPrivate filtering set to allow *you*
to block content; use the NoScript add on for Mozilla based browsers
(Firefox;SeaMonkey,etc) to block *all* scripts from running until *you*
allow them to run.

6) Install ToggleFlash for IE7/8 which blocks all Flash content from
running until *you* allow it to.

Or, install Spyware Blaster and allow it to block Flash content, ActiveX
controls, etc:

7) Install a trustworthy, dependable antivirus and keep it updated.
Opinions vary on which AV's qualify. I find Avast, NOD32, Vipre,
F-Secure, and Kaspersky AVs to be trustworthy and dependable without
adversely affecting system performance.
PLEASE NOTE: I do not include security suites as they do too many things
rather then just focus on preventing malware infestations.
