Java is a language that enables you to run applications on your computer. It’s also used to create web apps, commonly called “website scripts” or simply “web apps.” Java has been around for a long time—since 1995! But is it safe? Should I keep Java on my computer? And how do I know if I’m running an insecure version of Java? In this article, we’ll answer all of those questions and more.

Is it safe to download Java to my computer? Why or why not?

Is Java Safe To Download?

Java is a programming language that creates applications for web browsers, Android devices, and games. Java was created by Sun Microsystems in the 1990s and was later acquired by Oracle Corporation. It’s free and open-source software that you can download from Oracle’s website if you want to use it on your computer.

Java applications run inside of a virtual machine (VM), which means they don’t run directly on your computer like other programs such as Microsoft Word or iTunes do. The VM runs separately from other processes on your computer, so they don’t slow down anything you’re doing while using them.

When you install Java on your computer, it will create a separate folder where all the files needed to run your applications are stored. This folder is called a “JRE” folder and can be found in Documents > My Apps > Java.

There are two different versions of Java. They are called Java SE and Java ME. Java SE is usually used for applications like web browsers, while Java ME is used for mobile phones and other devices with limited processing power.

Problems with Java

The first thing to know is that Java has a bad reputation regarding security. Additionally, many believe that Java is vulnerable to attacks and should be avoided.

Because of its popularity and so many websites that rely on it, Java has been the target of many security breaches over the years. Hackers have exploited vulnerabilities in Java to launch attacks on computers for both personal gain and political reasons.

If you think about it, there are very few reasons why you would want something like this installed on your computer: not only does it leave you open to attack by hackers but also by viruses that use the same technology (like Flash) as an attack vector – meaning that any virus which can run on Windows can also run via Javascript!

There is little reason why anyone would need this software now unless they wanted access for some reason (e.g., developing software), but if this were so, then surely there would be other options available.

In short, if you don’t need it, then you should delete it.

If you’re reading this article, you are not a programmer and have little use for Java. You should uninstall it from your computer if this is the case. Many websites and other software programs on your computer use Java, so removing it can leave some applications inoperable until they are updated with an alternative implementation

If you need Java, it is best to keep it updated and use only trusted applications.

Do I Need to Uninstall Older Versions of Java from my Computer?

If you don’t use Java, get rid of it. You can install it again if you need it.

If you’re unsure whether or not to remove older versions of Java from your computer, here are some reasons why it might be good to do so:

  • Removing old versions will free up space on your hard drive, making room for new files and programs that need to be using up space in their installation directories.
  • The developers are constantly updating programs; removing old versions means you won’t have outdated software on your machine that could cause problems when trying out new apps or websites.
  • Older programs can also carry security risks if they are not kept up-to-date with patches and updates (which may take up more storage space). For example, Adobe Flash Player has been updated multiple times since its release in 1996—and though there haven’t been any major cybersecurity issues since then that we know about yet (knock on wood), keeping up with current technology will help ensure greater safety online as well as offline when interacting with others who might be running older systems!
  • It can be unpleasant to have so many old versions of programs installed on your computer, especially if you need to remember what they are for. If you think you’ll never use an older program again, then there’s no reason to keep it. Removing older programs also means that your system will run faster—because every file on your hard drive takes up some space, and deleting these files frees up more space for other things (like new apps or websites).

How to Protect Yourself from Attacks?

To protect yourself from attacks, you should:

  • Install a firewall and use it to block all traffic from the Internet unless you specifically allow it.
  • Install antivirus software on your computer. Update it regularly and ensure it has current definitions for protection against known viruses.
  • Keep your operating system updated with the latest patches and service packs available for your system so that any security holes discovered by hackers can be patched up before they are exploited by malicious code or applications. This also increases the chances of detecting intrusions early if one does occur on your computer or network.
  • Use an anti-malware program such as Malwarebytes AntiMalware or Spybot Search & Destroy to scan for and remove malware infections when detected (remember to update these programs’ virus definitions periodically). It is also recommended that you install an ad blocker program like AdAway (or uBlock Origin) which blocks ads from websites that could contain malicious code used in drive-by download attacks (it’s best not to visit websites that have popups).
  • Use a hard drive encryption program like VeraCrypt to encrypt the entire contents of your hard drive and prevent unauthorized access, even if someone steals your device. This is especially important if you store sensitive data such as passwords or financial information.

Should I Keep Java on My Computer?

It is safe to keep Java on your computer, but you should be aware of the different versions and install only the latest version. If you use an antivirus program, you can also set it up to alert you when new Java versions are released.

You can also use the Java Control Panel to check which version of Java you have installed and set up automatic updates for new versions.


We hope this article has helped you decide whether or not to keep Java on your computer. As we’ve shown, it can be beneficial in many situations, but some potential downsides may make you want to uninstall it. If you decide against keeping Java on your computer, uninstall it before installing any other programs.
