- via DrWeb, Dr.Web C&C Botnet HW-UUID checker
F-Secure provided removal instructions at Threat Description: Trojan-Downloader:OSX/Flashback.K. Because the OSX/Flashback Trojan uses a flaw in Oracle’s Java, F-Secure also provided instructions for Mac users to Update, Disable or Remove Your Java.
So, do Mac or Windows users really need Java? Following are reasons why someone may need Oracle Sun Java installed on their computer:
- Playing on-line games generally requires Java.
- With OpenOffice, Java is needed for the items listed here .
- It used to be that Java was needed for websites to be properly displayed. However, that is generally not the case now with Flash having taken over.
- There may be commercial programs that depend on Java. If Java is needed for a software installed on your computer, there should be a prompt for it.

The same is not the case for Mac users, although perhaps now they will see the light. Most antivirus vendors now provide licensed software specifically designed for Macs. There are also a few free programs available:
