Java exploits represent a common attack vector used by the bad guys to infiltrate vulnerable computers via the web browser. We wrote about the rise of Java exploits as early as 2010, and we haven't seen that trend decline. In fact, in the first quarter of 2013 alone, we've seen three Java remote code execution vulnerabilities being exploited in the wild: CVE-2013-0422, CVE-2013-0431, and CVE-2013-1493. In response, Oracle recently introduced a new security feature regarding the way unsigned Java applets and web start applications are run in the release of Java 7 update 11. The text in Oracle's release notes reads:

Synopsis: Default Security Level Setting Changed to High.

The default security level for Java applets and web start applications has been increased from "Medium" to "High". This affects the conditions under which unsigned (sandboxed) Java web applications can run. Previously, as long as you had the latest secure Java release installed applets and web start applications would continue to run as always. With the "High" setting the user is always warned before any unsigned application is run to prevent silent exploitation.

 

The rest is here.....

I uninstalled Java on my computer. I don't use it often enough to keep it installed and updated.

 

For some reason, I get a lot of strange looks ofr not having Java installed. My college's website shows a warning message telling me to install or enable Java, even though it doesn't use Java at all.

Can Java be uninstalled via control panel, and is it advised to uninstall it? I have recently been getting more and more Java updates. Not sure if it's legit.

You can remove it like this..

  1. Click Start
  2. Select Control Panel
  3. Select Programs
  4. Click Programs and Features
  5. Select the program you want to uninstall by clicking on it, and then click the Uninstall button.

 

A good article HERE

 

The only reason to leave it on would be for running Java applications, if you actually have any. In that case you would need to disable it in your browser(s) until needed.
