What is Pbrowserupd.exe process?

Pbrowserupd.exe is a malicious process created by coin miner virus

As I have specified in the introduction, Pbrowserupd.exe is a coin miner trojan virus. The names of the executive file may be diverse, however, the effects are usually the same. Considering that coin miners focus on cryptocurrency mining, they use all possible hardware capacity of your desktop to run this process. This virus doesn’t pay attention to the fact that you may want to make use of your device for other activities – it will constantly use over 80% of your CPU power.

Pbrowserupd.exe – Very high CPU as well as GPU use

Besides CPU usage, some of the coin miners additionally use GPU power for their tasks. In that situation, you will struggle also to see the mouse cursor moving – GPU is usually used on 100%. It is not as crucial as processor for system work, so Pbrowserupd.exe coin miner viruses do not waste time on trifles and utilize it all. It sometimes can result in sad results.

Shortly about cryptocurrency mining

Crypto mining is a term that means the action of calculating the transaction block hash. That is a basic element of anything based on the blockchain technology. Since this action takes a lot of calculations, a very strong desktop is required. Exactly, the GPU is better for this task, because they have more cores available. Cryptocurrency mining farms are usually constructed of tens and hundreds of video cards to conduct their activity effectively. Such computer systems are not usable for “general” purposes, like gaming or browsing the Web. Fraudsters who gain money via this coin miner use someones’ hardware instead, even if they are used for the regular activity.2

List of the typical coin miner symptoms

  • Extremely bad performance
  • CPU/GPU cooler fan creates a lot of noise
  • High temperature of the device (for laptops)
  • 80-90% consumption of CPU/GPU resources by an unknown process

    Coin miners does not deal damage to your files. However, they make a lot of unpleasant things with the whole system

    First of all, Pbrowserupd.exe virus makes your PC overloaded. It is not able to run your applications anymore, since all CPU power is used by a virus. That malware does not care for your demands, all it pays attention to is making money on you. Even if you are patient, and you waited until browser is open, you will likely suffer from exceptionally sluggish efficiency. Pages can open up for years, any sort of logins will take about a minute – just a horror story for a person that does a job online.

    “Visible” harm is not a solitary bad activity coin miners do to your personal computer. Pbrowserupd.exe coin miner additionally deals damage to your operating system. To carry out all malevolent operations effectively, it wrecks the security features of your system. You will likely see your Microsoft Defender disabled – malware halts it to prevent recognition. If you check the HOSTS file, you will likely see a ton of new entries – they are added by this trojan miner to connect your PC to a malicious cryptomining network. All these changes are about to be thrown back to the original in the process of computer recovery.

    Hardware effects of coin miner activity

    Besides slowing down your computer, running at peak power for long times may trigger damage to your machine and raise power bills. PC elements are designed to easily deal with high load, but they can do so only when they are in a good shape.

    Little and well-protected CPU cooling system is hard to damage. Meanwhile, GPUs have big and easy-to-access rotors, which can be easily broke if affected while working, for example, by the user much earlier before the malware injection. Malfunctioning cooling system, together with the really high load caused by Pbrowserupd.exe miner can easily lead to graphic card failure3. Video cards are also prone to have very fast wearing when utilized for crypto mining. It is likely a bad situation when the performance of your video card decreases on 20-30% just after several weeks of being used in such a way.

    How did I get Pbrowserupd.exe coin miner virus?

    Coin miners are spread through different ways, but their main sources are malicious banners and programs from dubious sources

    Coin miners are the most prevalent malicious programs among “serious” viruses. Adware sometimes acts as a carrier for Pbrowserupd.exe malware infiltration: it shows you the banners, which include a link to malware downloading. Sure, this abstract “malware” may belong to any type – yet another adware, spyware, rogue or backdoor. However, the statistics show that approximately 30% of all viruses spread with the malicious banners are coin miners – and Pbrowserupd.exe is right one of them.4

    Unwanted banners adware

    The example of malicious banners you can see in the Internet

    One more way you could get this thing on your PC is by downloading it from the untrustworthy web page as a part of a program. Users that spread hacked versions of well-known programs (which do not require the license key) have small chances to earn money. Therefore, there is a huge temptation to add malware to the final package of the hacked app and acquire a coin for each setup. Before blaming these people for hacking and also malware distribution, ask yourself – is it alright to avoid buying the program in this manner? It is much cheaper to pay $20-$30 at once than to pay a much greater figure for antivirus program and new parts for your PC.

    How to remove the Pbrowserupd.exe miner from my PC?

    The best way to get rid of this coin miner virus is to use anti-malware software

    Getting rid of such a virus demands making use of special tool. Appropriate security tool should have high performance at scanning and also be lightweight – in order to make no problems with usage also on weak systems. Furthermore, it is better to have proactive protection in your security solution – to prevent the virus even before it launches. Microsoft Defender does not have these functions for different factors. That’s why I’d advise you to use a third-party anti-malware program for that objective. GridinSoft Anti-Malware is a great choice that fits all of the specified qualities.5

    Before the malware removal, it is important to boot your system into Safe Mode with Networking.
