Prime Updater is a fake optimization tool that might install unwanted programs

The image of Prime Updater

Prime Updater is presented as a program that can automatically update all software on users' PCs. However, security experts tend to classify it as a potentially unwanted program[1] as it infiltrates users' machines without permission. Despite pretending to be useful, this software might install additional components that are useless (such as adware). The program might also be known as PrimeUp! to some users.

Name Prime Updater
Type Potentially unwanted program
Risk Medium. Might install PUPs or even malware
Distribution Software bundling
Elimination recommendations Download and install Reimage. Otherwise, you can check our manual removal instructions below

When users launch their browsers, on the right bottom corner, they find Pr Updater’s icon. In addition, users, who are used to check Task Manager occasionally, will find it running as primeupdater.exe. The application shows the list of currently available updates for Google Chrome, Mozilla Firefox, Skype, Adobe Flash and other popular programs. However, they are all fake. It’s easy to check if the program is playing with you.

For instance, if it delivers an update for Adobe Flash, visit the official site and install all available updates (if there are any). Within few minutes Prime Updater malware will show you “new” updates for Flash. Indeed, it’s a trick to convince people into agreeing to install suspicious components on their device that might mess up the system.

This program spreads in software bundles. Thus, it might enter the system silently and without asking direct permission. Once it’s installed, it creates Pr.Updater shortcut on the desktop and starts displaying misleading offers to update software. As we have mentioned in the beginning, this system tool is capable of installing other potentially unwanted or even malicious programs in the form of an update.

Prime Updater unwanted program

Users might also notice multitude of advertisements displayed on their Google Chrome, Mozilla Firefox, Internet Explorer, Mozilla Firefox or other browsers. These ads can be in various forms, including pop-ups, deals, offers, coupons, etc. This content might cover up the background of legitimate websites and disturb web browsing sessions. Additionally, redirects might lead victims to hacked, phishing[2] or malware-ridden websites.

Thus, in order to avoid infiltration of malware and disturbed browsing sessions, you have to remove Prime Updater immediately. It should be enough to uninstall this program from the Program’s list in the Control Panel. But sometimes, it manages to show up again. It’s possible that this application installs additional components that re-installs it after deletion.

For this reason, we suggest scanning the computer with Reimage, Malwarebytes or another reputable malware removal program and performing automatic Prime Updater removal. This method assures that all virus-related components are eliminated from the system entirely. Manual instructions that are listed below will help you get rid of Prime Updater manually.

Potentially unwanted programs infiltrate users' PCs via bundling

Developers of unwanted programs apply bundling technique to spread their applications. This software marketing method allows adding applications as an optional component in a software package. These potentially dangerous programs might be attached to any freeware or shareware.

The illustration of Prime Updater
Prime Updater shows the list of available updates. However installing them should not be considered because they are fake.

Thus, users who do not install new free programs carefully might unintentionally agree to install suspicious programs. When installing new programs, you have to choose Advanced/Custom installation wizard because it reveals the list of “optional downloads.” Meanwhile, Quick/Recommended settings do not have this function and install third-party components by default.

However, choosing Advanced settings is not enough. Also, you have to follow each of the steps carefully and unmark all pre-selected entries. What is more, you should also read Terms and Agreement, EULA[3] and Privacy Policy of the downloaded program. It helps to make sure that you do not agree to install the PUP or other malicious apps.

Prime Updater can be removed in two different ways

Prime Updater removal might be performed either manually or automatically. First of all, we suggest trying to get rid of this program manually. If it still shows up, then opt for the automatic option.

Therefore, go to the Add or Remove Programs (or Uninstall Programs) in Control Panel. Look through the list of installed programs. Once you find Pr.Updater, double-click on it and follow the uninstallation wizard. We also recommend looking up for other suspicious applications that might have also sneaked to your computer. It goes without saying that you have to uninstall them as well.

Prime Updater PUP

Then, check all your web browser and remove suspicious extensions too. We also suggest resetting browser’s settings in order to get rid of all virus-related entries. However, if this suspicious system tool still shows up, you should use additional help. In this case, you should remove Prime Updater virus using a reputable anti-malware program.

You can remove virus damage automatically with a help of one of these programs: Reimage, SpyHunter 5Combo Cleaner, Malwarebytes. We recommend these applications because they detect potentially unwanted programs and viruses with all their files and registry entries that are related to them.
