Symantec Security Response encourages all users and administrators to adhere to the following basic security “best practices” to prevent the virus attack to your computer:
1. Use a firewall to block all incoming connections from the Internet to services that should not be publicly available. By default, you should deny all incoming connections and only allow services you explicitly want to offer to the outside world.
2. Enforce a password policy. Complex passwords make it difficult to crack password files on compromised computers. This helps to prevent or limit damage when a computer is compromised.
3. Ensure that programs and users of the computer use the lowest level of privileges necessary to complete a task. When prompted for a root or UAC password, ensure that the program asking for administration-level access is a legitimate application. Read More»

That’s the latest update from security researchers who initially laid the blame on Microsoft’s Internet Explorer for the latest zero-day exploit that also can afflict those using the Firefox Web browser. Users could face a “highly critical” risk if they have both IE and Firefox version 2.0, or later, loaded on their computer.
