“Install Java Update” is a scam that tries to convince users to download adware or malware executables

"Install Java Update" scam pop-up"Install Java Update" is a fake alert that is triggered once a malicious website is visited.

“Install Java Update” is a fraudulent pop-up window that does not come from the official developer (Oracle) site website and can show up on Google Chrome, Internet Explorer, Mozilla Firefox, Safari, or any other installed browser. The fake alert indicates that your computer is running an outdated Java version and suggests you update it as soon as possible for the “improved computer performance.”

However, “Install Java Update” is a scam that helps criminals to distribute various high-risk computer infections. While in most of the cases you will encounter potentially unwanted programs promoted, other times, fake Java updates can distribute Trojans, backdoors, spyware or even ransomware. Likewise, you should never fall for “Download Java” fake update.

Therefore, you should never download anything which is offered to you through the bogus “Install Java Update” pop-up. Simply leave the malicious page without clicking anything. However, if redirects to scam sites, intrusive ads, slow browser operation, and other symptoms, your computer is likely suffering from the adware infection.

There are numerous similar scams to “Install Java Update” fake alert, such as “Adobe Flash Player Was Not Found,” “The Mercury Text Font Was Not Found,” etc. However, all of them are designed for the same purpose — infect the computers of inexperienced users via phishing[1] techniques. 

Users are redirected to “Download Java” page where they see the pop-up which states the following:

Download Java

Install Java Update

Your Java version may be outdated. It is strongly recommended to update your Java plugin now. Upgrading to the latest Java version improves the security of your system, as older versions do not include the latest security updates.

The latest Java version contains important enhancements to improve your computer performance:

Allows you to see web content properly;
Safe and secure;
Free Software.
Update Version: 8u111

If you have been redirected to Download Java page, you must immediately leave it and do NOT click on the download button. If you struggle to leave the page, open the Task Manager, and shut down the browser from there.

Fake “Install Java Update” prompt is likely caused by an adware infection. Such potentially unwanted programs (PUPs) are designed to deliver advertising and often potentially dangerous content for the owner of the computer. Likewise, an ad-supported application will continue to display fake alerts as long as you keep it on your system.

"Install Java Update" alert"Install Java Update" is a scam which says that the user should download a new version of Java. However, once the download button is clicked, user's computer gets infected with malware.

Unfortunately, by downloading “Install Java Update” virus executable (often labeled as “javaupdate11.jar, update.exe, Java.exe, and similar), you will most likely be injecting more ad-supported programs on your computer. Also, because most PUPs are quite deceptive, it might be difficult to detect them all and eliminate.

In such a case, you should use ReimageIntego or another security software to remove “Install Java Update” alerts from your browsers along with all the unwanted apps on your machine. The examples of the downloaded PUPs via the fake update includes Trovi Search, MyCouponize, Spigot ToolbarMergeDocsNow, etc.

If you encountered “Install Java Update” pop-up just once or twice, it does not mean that your computer is infected. However, you should watch out for the following adware infection symptoms:

  • Pop-ups, coupons, banners, offers, deals, and other advertisements are displayed on all sites that you visit;
  • You see sponsored links at the top of search results;
  • Suspicious applications or browser extensions installed without your permission;
  • Desktop shortcuts changed and link to suspicious sites;
  • Homepage, new tab URL and the search engine of the browser changed;
  • The browser takes much longer to load up websites, and you are after redirected several times before landing on the destination page.

Be aware that you might experience some or all of the symptoms listed below. However, for “Install Java Update” removal from your browsers, you should check the installed program list via the Control Panel (Windows) or Settings > Apps (Android). You will find detailed instructions for that below.

"Install Java Update" different versionsThere are multiple different versions of "Install Java Update" scam - do not fall victim of any of those - always download Java from the official website

Some programs still use Java, but most regular users don't need it in the first place

Java is a popular programming language, and its software is run on 3 billion devices, as Oracle claims. It is usually installed together with software that uses the language, and cannot be run without it. Correspondingly, some websites might also be made in Java and would be not accessible without it.

However, Java is rarely needed by regular users,[2] unless they run specific software that requires Java to run. Besides, very few websites are using Java nowadays, so there is no need for software in the first place. Keep in mind that Java is also often targeted by cybercriminals and riddled with vulnerabilities[3] – these can be abused if the software is not patched with the latest updates.

Nevertheless, if you indeed run programs that use Java, you should always make sure that the updates for it are downloaded from the official Oracle's website ( The best solution would be to set the updates of the program to run automatically, so you would not have to worry about fake versions.

Java's installer is also responsible for bundling unwanted apps like Ask Toolbar and other suspicious software that spams users with ads without providing many benefits. What is worse, is that at least two optional components are included with every single Java update that comes out and users have to decline them.[4] As usual, most are quick to get through the installation process to install what's needed, and then end up with unwanted apps on their systems. However, you can find out more about that in the next section.

Official Java download siteMost likely, you do not need Java on your computer. In case you do, always make sure you download updates from the official website or set them to be downloaded automatically via the application.

Paying attention to the installation of freeware is the only way to avoid adware infections

If you wonder how did adware get on your system, the answer is simple. Developers employ an unfair, but legal distribution method, which is called bundling[5]. It allows the contrivers to offer potentially unwanted programs together with third-party applications in one package. In other terms, people who want to download only the freeware will additionally get the adware as well.

Even though developers do not inform their customers about such actions, you can easily detect potentially unwanted programs in software-bundles if you choose Custom/Advanced mode during the installation. These parameters do not skip steps and reveal optional components which are hidden in Recommended/Quick settings.

In case you notice any suspicious pre-selected boxes like “I agree to install XXX,” “Get XXX now” and similar claims, immediately de-select them. Being cautious during the installation of freeware is the only way how you can avoid the infiltration of potentially unwanted programs.

Additionally, you should stay away from suspicious and shady websites. Typically they are designed to distribute numerous potentially dangerous programs, like spyware, Trojan horses, etc. Also, download software and their updates only from official websites or authorized distributors.

Protect your privacy – employ a VPN

There are several ways how to make your online time more private – you can access an incognito tab. However, there is no secret that even in this mode, you are tracked for advertising purposes. There is a way to add an extra layer of protection and create a completely anonymous web browsing practice with the help of Private Internet Access VPN. This software reroutes traffic through different servers, thus leaving your IP address and geolocation in disguise. Besides, it is based on a strict no-log policy, meaning that no data will be recorded, leaked, and available for both first and third parties. The combination of a secure web browser and Private Internet Access VPN will let you browse the Internet without a feeling of being spied or targeted by criminals. 

No backups? No problem. Use a data recovery tool

If you wonder how data loss can occur, you should not look any further for answers – human errors, malware attacks, hardware failures, power cuts, natural disasters, or even simple negligence. In some cases, lost files are extremely important, and many straight out panic when such an unfortunate course of events happen. Due to this, you should always ensure that you prepare proper data backups on a regular basis.

If you were caught by surprise and did not have any backups to restore your files from, not everything is lost. Data Recovery Pro is one of the leading file recovery solutions you can find on the market – it is likely to restore even lost emails or data located on an external device.
