April Fool's Conficker Threat

Despite warnings of digital Armageddon come April 1, experts say you can probably breathe easy.

There's some serious speculation out there right now about what the Conficker worm will do on April 1. But according to those in the know, you probably don't have to worry.

According to Joe Stewart, a security researcher at SecureWorks who knows what's what when it comes to malware, "there will be no April 1st outbreak." Clean PCs won't suddenly melt down from a new Conficker infection. All that will happen, Stewart writes, is that the worm will begin to use a new trick that gives it a better chance of getting around existing defenses that attempt to prevent it from updating. The ability has been around since a new Conficker variant came out earlier this month

if you're not infected on April 1, nothing will happen to you. If you are infected with Conficker, it will attempt to update itself. That update could theoretically contain instructions to do something drastic, like wiping out a hard drive, but that's pretty unlikely. Conficker's creators stand to gain nothing by such a destructive act, and malware these days is all about gain.

And there's a relatively simple check to see if you're infected with Conficker: Point your browser towards f-secure.com, secureworks.com, microsoft.com or other security sites. If you get a "page cannot be displayed" error for all the sites, there's a good chance they're blocked by Conficker or similar malware on your PC.

If that happens to you, you'd also be blocked from normally downloading free Conficker removal tools. But you can get around the malware blocks by using a Web proxy or alternate download links, according to Stewart.
