Java memory use

[Alias]

How this is the proper forum. Running W8.1. My system has been slow for a few months. A little slow on bootup, VERY slow after 2-3 days.
For example, after 2-3 days, it takes 2-3 minutes for Word to open. 4 minutes for an email to fully open. Pushing the Windows button can take 3-5 minutes to get the Windows screen. Reboot takes me back to 'a little slow.'
I ran the last week with resmon open and watched RAM use. The biggest culprit it Firefox, which, after 2-3 days takes up 1.8-1.9G of my 4G RAM. I've since gone to using IE. 2dn biggest user is JAVA, which uses 0.7-0.9G RAM. Is this normal? If not, how do I find the cause?

JAVA has had security issues for some while now and I understand very few programs require it these days. It must be over 2 years now sonce I uninstalled JAVA from my installed programs list and I have not come across any prompts asking me to install it because the program requires it. I suggest you uninstall JAVA and you will get back that 0.9GB RAM it is using.

Thanks for the reply. Control Panel>Programs and Features>Uninstall.
Java isn't there. How do I delete it.

Open Task Manager (TM) and select the "Processes" tab. Find and select "Java" then click on "End Task". Also in TM click on the "Start-up" tab, select "Java" then click on "Disable". If you find that some program shows a pop-up stating that Java is not running and asks you to enable it then that program has security issues and I would ignore the pop-up. Modern, security concious program writers should not be using Java.
