The hacker scripts try to infect site visitors and then attempt to use their compromised PCs to spread the infection to yet other sites.
Security updates for all versions of Internet Explorer have been released this week, although Microsoft rates as “Critical” only the patches for IE 8 (on all versions of Windows) and IE 7 (Vista SP2).
Version 8 of Microsoft’s browser is now being included in automatic Windows updates for all users, so be sure to uncheck the IE 8 option if for any reason you wish to postpone upgrading from IE 7 to IE 8.

to build new systems without installing the trouble-prone Windows Genuine Advantage app, you may want to patch your PC using something other than Windows Update, which offers again and again to install WGA.
My favorite third-party software update service is currently the Shavlik Patch Google Gadget, although Secunia’s Personal Software Inspector is a worthwhile alternative.
You may already have been offered version 8 of Microsoft’s Internet Explorer browser via Windows’ built-in Automatic Updates routine, but you should be aware that some Web sites don’t work with the new release.
In my testing, IE 8’s security and compatibility settings cause problems with some sites, and XP users must first uninstall SP3 in order to remove the latest build of IE.
If you’re a legitimate Microsoft customer, you can download and install all the Windows updates you need without running Windows Genuine Advantage (WGA) and exposing yourself to the false positives it’s become known for.
In today’s article, I explain how to install Windows XP and upgrade it with every available security fix and many optional updates as well, without ever installing WGA.

Two separate updates for all IE versions prevent carpet-bombing attacks that are already targeting the browser.
One of the IE patches blocks remote-code execution on XP and Vista PCs that also have Apple’s Safari browser installed.
Windows may be the primary target of today’s malware authors, but it’s far from the only one.
Keeping your applications and media players up-to-date is as important as applying the latest patches for your operating system.
