Please update all internet browsers and operating systems today and for the remainder of the week to insure you have the latest patch for Java on your systems.
If you have developers, they can download the Java patch at: http://www.oracle.com/technetwork/java/javase/downloads/index.html
The Java flaw announced over the weekend has been fixed according to Oracle, the current owner of Java.
The patch should be released later today but until you have the patch, you are not safe.
Please note, although Oracle indicated this bug only applied to Java 7, which is the latest release, because you cannot be certain the flaw is only in that version, please update everything.

Probably yes. The Java problem was widespread and impacted Windows, Apple, and Linux machines.
