Update
TrendLabs has discovered a new Conficker variant (detected as WORM_DOWNAD.E). It appears that this may be the activity that was supposed to happen on April 1st. This new variant only affects those PCs that have been previously infected with WORM_DOWNAD.KK. If your customers' Trend Micro products have been patched and they are running the latest engines and pattern files, they are protected from this variant.
To make sure your system is protected, make sure that you have installed all of the security patches for Microsoft Windows operating systems, particularly Patch MS08067. Make sure your system is configured to receive security updates and patches from Microsoft as well as other 3rd party vendors automatically.
Make sure your security software such as Trend Micro, Symantec, or McAfee is up to date.
Make sure you disable the “Drive Auto-run” feature to avoid infections from USB drives.
You should employ secure passwords using a combination of letters, numbers and symbols and frequently change them.
Make sure to take caution when searching online for DOWNAD and Conficker information. There are reports of rogue antivirus packages that are taking advantage of the situation. They will tell you that you are infected and ask you to pay money to download their application, which in many cases turns out to be malware.
