What is Viewndow.exe process?

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

As I have mentioned earlier, Viewndow.exe is a coin miner trojan virus. The names of the executive file may be diverse, but the impacts are almost always the same. Because coin miners focus on cryptocurrency mining, they utilize all available hardware power of your personal computer to run this operation. This malware does not pay attention to the fact that you may want to make use of your machine for other activities – it will consistently use over 80% of your CPU power.

Viewndow.exe – Extremely high CPU/GPU usage

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

Shortly about cryptocurrency mining

Crypto mining is a term that means the activity of calculating the transaction block hash. That is a basic element of any project based on the blockchain technology. Since this action takes a lot of calculations, a strong computer is needed. Exactly, the graphic card is better for this task, because they have more cores available. Cryptocurrency mining farms usually consist of tens and hundreds of graphic cards to complete their task efficiently. Such computer systems are not usable for “normal” purposes, like gaming or browsing the Web. Crooks who gain money via this coin miner use someones’ computers 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
  • How dangerous is the Viewndow.exe miner?

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

    First of all, Viewndow.exe virus makes your PC overloaded. It is unable to run your applications anymore, as all CPU power is used by a malware. That malware does not care for your needs, all it focuses on is generating profits on you. Even if you are patient, and you waited until web browser is open, you will likely suffer from exceptionally slow efficiency. Pages can open for years, any sort of logins will take about a minute – just a horror story for a person who does a job online.

    “Visible” harm is not a single negative thing coin miners perform to your PC. Viewndow.exe coin miner additionally deals damage to your OS. To carry out all malicious functions successfully, it ruins the protection components of your system. You will likely see your Microsoft Defender disabled – malware halts it to prevent recognition. If you open the HOSTS file, you will likely see a lot of new notes – they are brought in by this trojan miner to connect your PC to a malicious mining network. All these adjustments are about to be gone back to the initial state in the process of system recovery.

    Hardware effects of coin miner activity

    Besides making your PC slow, running at peak power for long times may trigger damage to your device as well as raise electricity costs. PC components are designed to easily get along with high load, but they are good with it only when they are in a good shape.

    Compact and well-protected processor fan is hard to broke. Meanwhile, graphic cards have big and easy-to-access fans, which can be easily cracked if touched while spinning, for example, by the user much before the malware injection. Malfunctioning cooling system, together with the extremely high load caused by Viewndow.exe malware can easily lead to GPU failure3. Video cards are also prone to have fast wearing when utilized for crypto mining. It is likely an undesirable situation when your GPU’s performance plunges 20-30% only after several weeks of being used in such a way.

    How did I get Viewndow.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 through “major” malware. Adware frequently serves as a carrier for Viewndow.exe malware injection: it demonstrates you the banners, which include a link to malware downloading. Yes, this abstract “malware” may belong to any type – yet another adware, spyware, rogue or backdoor. But the statistics show that around 30% of all viruses spread through the malevolent banners are coin miners – and Viewndow.exe is just with them.4

    Unwanted banners adware

    The example of malicious banners you can see in the Internet

    Another way you could get this thing on your computer is by downloading it from the unreliable site as a part of a program. People that spread hacked variants of well-known programs (which do not require the license key) have small chances to get paid. Hence, there is a very big temptation to include malware to the final package of the hacked app and receive a coin for each setup. Prior to blaming these individuals for hacking and also malware distribution, ask yourself – is it alright to avoid paying for the program in such a way? It is much cheaper to pay $20-$30 at once than to pay a much greater sum for antivirus program and new parts for your computer.

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

    Getting rid of such a virus involves making use of special program. Proper anti-malware program must have high capability at scanning and also be lightweight – in order to make no problems with usage even on weak computers. Furthermore, it is better to have proactive protection in your security solution – to stop the virus even before it launches. Microsoft Defender lacks these features for different reasons. That’s why I’d suggest you to use a third-party anti-malware program for that purpose. GridinSoft Anti-Malware is an ideal choice that fits all of the discussed features.5
