If you think your computer system might be infected by Conficker Worm, there is something you might be able to do about it. First, you need to find out if your system is indeed infected. Visit any security website (try Symantec, Norton, BitDefender, or Kaspersky). If you can log onto these sites, your computer is not infected, Conficker blocks access to most security websites. If you try to log onto any of these websites and access to them has been blocked, then your system may have been infected by Conficker Worm. Follow the steps below provided by Symantec.com to get rid of Conficker.

If you have a computer that is infected, you will need to use an uninfected computer to download a specialized Conficker removal tool from. The tool is available here:

Or, you can restore access to security web sites on an infected machine by taking the following steps:

Click Start > Run.
In the Run box, type the following: cmd
Click OK.
Type the following and then press Enter. cd..
Repeat the previous step until you get to the root level, or C:\>. Note that if your root drive is not C, the letter will be different.
At C:\> type the following: net stop dnscache
Press Enter. This disables the domain blocking feature of Conficker and you should now be able to reach security Web sites including ours. You should now be able to download the Conficker removal tool here.

Advice to Stay Safe from the Downadup Worm:Run a good security suite (we are partial to Norton Internet Security 2010 and Norton 360 Version 4.0).
Keep your computer updated with the latest patches. If you don’t know how to do this, have someone help you set your system to update itself.
Don’t use “free” security scans that pop up on many web sites. All too often these are fake, using scare tactics to try to get you to purchase their “full” service. In many cases these are actually infecting you while they run. There is reason to believe that the creators of the Conficker worm are associated with some of these fake security products.
Turn off the “autorun” feature that will automatically run programs found on memory sticks and other USB devices.
Be smart with your passwords. This includes
Change your passwords periodically
Use complex passwords – no simple names or words, use special characters and numbers
Using a separate, longer password for each site that has sensitive personal information or access to your bank accounts or credit cards.
Use a passwords management system such as Identity Safe (included in Norton Internet Security 2010 and Norton 360 Version 4.0) to track your passwords and to fill out forms automatically.
Run Norton Internet Security 2010, Norton AntiVirus 2010 or Norton 360 Version 4.0. You can also try Norton Security Scan.
