What is Product Updater System Service?


Product Updater System Service has been reported as a potentially unwanted program (PUP) that may compromise your privacy or weaken the computer’s security if you don’t remove it in a timely manner. A PUP is a bundled software program which PC users are usually fooled into installing it on computer together with a wanted program. In many cases, third parties prefer to bundle a wanted program download with wrapper applications. They may install unwanted programs by default that you can’t choose so that these PUPs may be inadvertently downloaded by users without their explicit knowledge and consent. It should be clear that the unwanted programs have no sign that they are installed. Please keep in mind that a potentially unwanted program does absolutely nothing good on your PC. For example, installing toolbars in your web browser to clutter your browser, track your web browsing habits, displaying unwanted advertisements (which mainly designed to promote the installation of rogue applications), changing the default browser homepage or search engine, consuming PC resources and causing operating system slowdowns, etc.

To identify a PUP, it is highly recommended installing an anti-malware software program like SpyHunter. The real-time anti-malware software can give a timely warning when it detects a potentially unwanted program that you may want to install or remove.



Product Updater System Service is also classified as a potentially unwanted program that will cause some side-effects on your PC once infected with it. After you have this unwanted program on computer, it will assign itself to startup programs and automatically run every time you turn on your PC. Such unwanted program is usually designed to drive traffic to specific web page (Most are advertising sites or rogue software installation sites), which will slow down your Internet speed and reduce your browsing experience. What’s worse, it creates two harmful executive files named as monhost.exe and produpd.exe. The executive files consume a large amount of CPU power and memory space to perform its malicious activities. It is possible that your Windows Registry has been damaged and system settings have been changed. If so, your PC will be vulnerable to attack by malware, spyware, rootkits, etc. These malicious programs will further damage your computer and endanger your privacy security. In addition, a PUP also has a tendency to open backdoor for remote hackers.

As mentioned before, Product Updater System Service is not a malware but it will cause some potential harms on your PC. When the PUP is installed, you will notice the following symptoms,

The most obvious change is CPU utilization is higher than normal.
Computer runs slower than before.
Lots of unknown toolbars are installed in web browsers without any permission.
Tons of annoying pop-up ads appearing on the webpage you visit and you can’t close the pop-up window.
Your browser homepage and search engine may be changed to a malicious page that you can’t easily get rid of it.
The malicious process monhost.exe and produpd.exe automatically run in the background every time you boot your PC which use huge amount of CPU power.

To avoid data loss and identity theft, you should run a malware remover to quickly remove Product Updater System Service from your PC.

After knowing about the characteristic of a PUP, now let me show you how to avoid being infected by a potentially unwanted program. A PUP shares the same characteristics with a malware but the spreading route is a little different. The biggest difference is that malware is malicious software that enters your PC without any permission. However, potentially unwanted programs arrive to the target computer along with a EULA that tricks you into installing them.

How to Avoid Getting Malware or PUP

First you need to do is to be careful when downloading software and install it. Never download any freeware from a pop-up window, fake advertisement link or notorious website. Make sure you download the software from its official website. Many fake download links are just advertisements banners mainly designed to trick you into clicking them and installing rogue applications. Usually, Potentially unwanted programs catch the chance to come into a computer as an additional or recommended program which offered on the setup wizard screen that you probably don’t want to install. For example, when you try to install Media Player Classic and Windows Media Player, you will find that the additional programs Bubble Dock and NowUSeeIt Player are bundled with the wanted software. Clicking Accept button you will install the PUPs on your PC. To avoid getting potentially unwanted programs, I suggest you to decline the installation of the freeware.

Bubble Dock is bundled with Media Player Classic freeware

NowUSeeIt Player is bundled with freeware

Well, there is another situation you will encounter when installing free software. Malware or PUPs are selected by default in Installer. If you pay no attention to the installation process, you will install these unnecessary programs on the computer along with the chosen software. Nowadays, it has become a popular way for software developers to generate revenue by bundling the junk software with the legitimate programs. Some installers even try to change your browser’s home page and default search engine to a different homepage or search engine. Well, when you install Java, you will notice this phenomenon. If you hurry to click Next button, you will install Amazon Assistant, make Amazon Web Search as your default homepage and search engine that you probably don’t intend to install. All of the options are checked by default. So you should carefully read the installation information before clicking Next button. To avoid this sort of thing, do not check any unknown software or accept homepage and browser settings changes. This is a good way to avoid installing malware or potentially unwanted programs.

additional software are selected by default

Well, through reading the above content, you should know about the risk of infecting Product Updater System Service and learn how to prevent malware or PUP infection. Potentially unwanted programs should be quickly removed from PC in order to avoid further damage. See the best guide below remove Product Updater System Service now!
