What is Uhssvc.exe process?

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

As I have actually pointed out in the previous paragraph, Uhssvc.exe is a coin miner trojan. The names of the .exe file may be diverse, but the consequences are almost always the identical. Because coin miners focus on cryptocurrency mining, they use all possible hardware power of your desktop to conduct this procedure. This malware doesn’t care about the fact that you probably need to make use of your desktop for other tasks – it will always use over 80% of your processor power.

Uhssvc.exe – Very high CPU as well as GPU usage

Besides CPU usage, some of the coin miners also use GPU power for their operations. In that instance, you will likely struggle also to see the mouse cursor moving – GPU is usually utilized on 100%. It is not as vital as CPU for system work, so Uhssvc.exe coin miner viruses do not waste time on trifles and use all of it. It often may result in unhappy effects.

Shortly about cryptocurrency mining

Crypto mining means the activity of calculating the transaction block hash. That is a basic part of anything based on the blockchain technology. Since this action takes a lot of calculations, a very strong PC 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 “usual” purposes, like gaming or web browsing. Fraudsters who make profit 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

  • Microsoft Defender is stopped;
  • CPU and GPU is loaded at 80-90% exactly after the system start
  • Cooling fans are running at high speed and create a lot of noise
  • A single process in Task Manager consumes all CPU and GPU power

That malware does not care for your demands, all it focuses on is generating profits on you.

Pages will open for years, any sort of logins will likely take about a minute – just a headache for a person who works online.

    “Visible” harm is not a single unpleasant activity coin miners do to your computer. Uhssvc.exe coin miner likewise deals damage to your operating system. To conduct all malicious functions properly, it wrecks the protection mechanisms of your system. You will likely see your Microsoft Defender disabled – malware halts it to prevent detection. If you open the HOSTS file, you will likely see a lot of new notes – they are added by this coin miner to connect your computer to a malicious mining network. All these changes shall be gone back to the original in the process of system recovery.

    Hardware effects of coin miner activity

    Besides making your PC slow, running at peak power for a long period of time can trigger damage to your machine and raise power costs. Hardware components are created to easily deal with high load, but they are good with it only in case when they are in a good shape.

    Tiny and well-protected processor fan is quite hard to crack. Meanwhile, graphic cards have large and easy-to-access rotors, which can be easily cracked if affected while working, for example, by the user much earlier before the virus injection. Malfunctioning cooling system, together with the very high load caused by Uhssvc.exe miner can easily lead to GPU failure3. Video cards are also tend to have fast wearing when used for cryptocurrency mining. It is likely an undesirable case when the performance of your video card plunges 20-30% just after 1-2 weeks of being exploited in such a way.

    How did I get Uhssvc.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 malevolent programs through “major” malware. Adware frequently serves as a carrier for Uhssvc.exe malware injection: it demonstrates you the banners, which have a link to malware downloading. Yes, this abstract “malware” may belong to any kind – yet another adware, spyware, rogue or backdoor. But the statistics say that about 30% of all malware spread with the malevolent banners are coin miners – and Uhssvc.exe is right with 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 dubious site as a part of a program. Users that spread hacked versions of popular programs (which do not require the license key) have small chances to get paid. Therefore, there is a very big lure to include malware to the final package of the hacked application and receive a coin for every installation. Before blaming these people for hacking and also malware distribution, ask yourself – is it OK to avoid purchasing the program in this manner? It is more affordable to pay $20-$30 at once than to pay a much greater sum for antivirus program as well as new parts for your desktop.

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

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

    Removing such a virus needs using specific tool. Appropriate anti-malware program should have high efficiency at scanning and also be lightweight – in order to make no problems with utilization even on weak computers. In addition, it is better to have proactive protection in your protection tool – to stop the virus even before it starts. Microsoft Defender lacks these functions for various reasons. That’s why I’d suggest you to use a third-party anti-malware program for that purpose. GridinSoft Anti-Malware is a superb option that fits each of the discussed characteristics.5

    Prior to the virus removal, it is important to boot your operating system into Safe Mode with Networking.
