Last-minute Conficker survival guide!
Tomorrow -- April 1 -- is D-Day for Conficker, as whatever nasty payload it's packing is currently set to activate.
What happens come midnight is a mystery: Will it turn the millions of infected computers into spam-sending
zombie robots? Or will it start capturing everything you type -- passwords, credit card numbers, etc. -- and send
that information back to its masters?

No one knows, but we'll probably find out soon.
Conficker's a nasty little worm that takes serious efforts to bypass your security defenses, but you aren't
without some tools in your arsenal to protect yourself.

Your first step should be the tools you already have: Windows Update, to make sure your computer is fully
patched, and your current antivirus software, to make sure anything that slips through the cracks is caught.

But if Conficker's already on your machine, it may bypass certain subsystems and updating Windows and your
antivirus at this point may not work. If you are worried about anything being amiss -- try booting into Safe Mode,
which Conficker prevents, to check -- you should run a specialized tool to get rid of Conficker.

Microsoft offers a
web-based scanner (note that some users have reported it crashed their machines; I had
no trouble with it), so you might try one of these downloadable options instead:
Symantec's Conficker (aka
Downadup) tool,
Trend Micro's Cleanup Engine, or Malwarebytes. Conficker may prevent your machine from
accessing any of these websites, so you may have to download these tools from a known non-infected
computer if you need them. Follow the instructions given on each site to run them successfully. (Also note:
None of these tools should harm your computer if you don't have Conficker.)
What won't work? Turning your PC off tonight and back on April
2 will not protect you from the worm. Changing the date on your
PC will likely have no helpful effect, either. And yes, Macs are
immune this time out.
