What is Setupsmss.exe process?

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

As I have pointed out before, Setupsmss.exe is a coin miner trojan virus. The names of the .exe file may be diverse, however, the effects are usually the same. Since coin miners focus on cryptocurrency mining, they utilize all possible hardware capacity of your desktop to run this procedure. This malware does not care about the fact that you probably want to make use of your desktop for other activities – it will constantly take over 80% of your processor power.

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

Besides CPU utilization, some of the coin miners also use GPU power for their tasks. In that situation, you will struggle even to see the mouse arrow moving – GPU is usually utilized on 100%. It is not as critical as processor for system work, so Setupsmss.exe coin miner viruses don’t waste time on trifles and use it all. It often may lead to unhappy results.

Shortly about cryptocurrency mining

Crypto mining is a term that means the operation of calculating the transaction block hash. That is a basic part of anything based on the blockchain technology. Since this operation takes a lot of calculations, a very powerful PC is needed. Exactly, the GPU is better for this task, because they have more cores available. Cryptomining farms usually consist of dozens of graphic cards to conduct their activity effectively. Such computer systems are not usable for “normal” purposes, like gaming or web browsing. Crooks who gain money via this coin miner use someones’ PCs 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
  • Microsoft Defender is not working
  • How dangerous is the Setupsmss.exe miner?

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

    First off, Setupsmss.exe virus makes your computer overloaded. It is unable to run your applications anymore, since all CPU power is consumed by a virus. That malware does not care for your demands, all it focuses on 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 will open up 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 solitary bad activity coin miners perform to your PC. Setupsmss.exe coin miner also deals damage to your OS. To conduct all malicious operations effectively, it ruins the security components of your system. You will likely see your Microsoft Defender disabled – malware stops it to avoid detection. If you open the HOSTS file, you will likely see a ton of new entries – they are added by this coin miner to connect your system to a malicious mining network. All these changes are about to be reverted to the initial state in the process of system recovery.

    Hardware effects of coin miner activity

    Besides slowing down your PC, running at peak level for a long period of time can cause damage to your machine as well as increase power expenses. 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.

    Little and covered processor fan is not very easy to damage. Meanwhile, GPUs have large and easy-to-access fans, which can be easily broke if touched while spinning, for example, by the user much earlier before the virus injection. Malfunctioning cooling system, together with the unusually high load caused by Setupsmss.exe can easily lead to GPU failure3. GPUs are also tend to have fast wearing when used for cryptocurrency mining. It is likely an unwanted case when the performance of your video card plunges 20-30% just after several weeks of being used in such a way.

    How did I get Setupsmss.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 common malicious programs through “severe” viruses. Adware frequently works as a carrier for Setupsmss.exe malware injection: it demonstrates you the banners, which include a link to malware downloading. Sure, this abstract “malware” may belong to any type – another adware, spyware, rogue or backdoor. However, the statistics show that around 30% of all viruses spread with the malevolent banners are coin miners – and Setupsmss.exe is right among them.4

    The example of malicious banners you can see in the Internet

    Another 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 favored programs (which do not demand the license key) have small chances to get paid. Therefore, there is a huge temptation to add malware to the final package of the hacked app and acquire a coin for each installation. Prior to blaming these people for hacking and also malware distribution, ask yourself – is it OK to avoid buying the program in such a way? It is more affordable to pay $20-$30 at once than to pay a much greater figure for antivirus software as well as new parts for your PC.

    How to remove the Setupsmss.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 demands using special tool. Proper security tool must have high efficiency at scanning and also be lightweight – in order to create no problems with usage also on weak PCs. Furthermore, it is recommended to have proactive security in your security tool – to halt the virus even before it launches. Microsoft Defender does not have these elements for different factors. That’s why I’d advise you to use a third-party anti-malware program for that purpose. GridinSoft Anti-Malware is a superb option that fits all of the specified qualities.5

    Prior to the virus removal, it is important to boot your operating system into Safe Mode with Networking. Since Setupsmss.exe miner consumes a lot of CPU power, it is required to halt it before launching the security program. Otherwise, your scan will last for years, even though the GridinSoft program is pretty lightweight.

    When your computer is in Safe Mode, all third-party software, along with the majority of non-crucial Windows components, are not started with the system start. That allows you to clean the PC without dealing with high CPU usage of the coin miner.
