The DNSChanger malware that was the original subject for this thread is apparently still active, and some slightly modified instructions for checkout have appeared.

The FBI received court approval to continue operating their redirect-redirecting phony websites for those who hadn't removed the malware. This apparently applied (and may still apply) to fairly large numbers of computers.

The NEW DATE on which the FBI servers will shut down is July 09, 2012.

Anyone still infected by this malware after that date will have NO INTERNET CONTACT.

The original instruction to visit this FBI-backed website, DNS-OK, is still good. If you see a RED background there, it definietely means you ARE infected. If you see a GREEN background, you probably are not infected.

It has been determined that if you ISP is redirecting DNS requests, you may see the green at that site while your computer still is infected, so a second check is recommended.

If you see RED at the FBI site you know you need to fix it.

If you see GREEN at the FBI site above you still are advised to go to this site, run by the DNS Changer Working Group. The DNS Changer Working Group will direct you to a URL appropriate to your language and location, that will detect more specifically whether your computer has been "violated," and if so, will point you to the right fix for your computer.

(Not that if you saw the GREEN when this thread started, it still might be a good idea to click to the second site now just to be sure, since that's based on newer information.)

This information is from July 9 could be 'Internet doomsday' for some (so check your PC or Mac), posted a few hours ago.
