The Java spike in Q3 is primarily driven by attacks on three vulnerabilities, which all, by the way, have had patches available for them for some time now. The first two, in particular, have gone from hundreds of thousands per quarter to millions:
CVE Attacks Computers Description CVE-2008-5353 3,560,669 1,196,480 A deserialization issue in vulnerable versions of JRE (Java Runtime Environment) allows remote code execution through Java-enabled browsers on multiple platforms, such as Microsoft Windows, Linux, and Apple Mac OS X.

Whether you keep Java or decide to uninstall it from your computer, it is necessary to look not only for the Java(TM) 6 Update (number) but also for any installation with J2SE, Java(TM) 5, or Java(TM) SE Runtime Environment 6. It is also advisable to remove the leftover files in your downloads folder.
In the event you keep Java installed, there should only be the current version in add/remove programs (as of this posting, Java(TM) 6 Update 22, available at Java SE Runtime Environment 6u22).
Since Java updates tend to leave leftovers, JavaRa is recommended. Freð ðe Vries provided notice that JavaRa has been silently updated to reflect the publication of Oracle's Java JRE 184.108.40.206. Leftovers up to Oracle Sun Java 220.127.116.11 are now cleaned by JavaRa. Simply download JavaRa and unzip it to your desktop.
- Double-click on JavaRa.exe to start the program. (Windows Vista and Windows 7 users right-click JavaRa.exe > Select Run as Administrator)
- Click on Remove Older Versions to remove older versions of Java.
Confirm that the following folders a have also been removed:
