What is Diagscap.exe process?

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

As I have actually pointed out previously, Diagscap.exe is a coin miner virus. The names of the .exe file may be diverse, but the impacts are almost always the identical. Considering that coin miners aim at cryptocurrency mining, they utilize all possible hardware capacity of your desktop to conduct this procedure. This malware doesn’t pay attention to the fact that you probably need to make use of your computer for other activities – it will consistently consume over 80% of your CPU power.

Diagscap.exe – Really high CPU as well as GPU usage

Besides CPU utilization, some of the coin miners also utilize GPU power for their tasks. In that instance, you will probably struggle also to see the mouse arrow moving – GPU is usually used on 100%. It is not as vital as CPU for system work, so Diagscap.exe coin miner viruses don’t waste time on trifles and use all of it. It often can lead to sad effects.

Shortly about cryptocurrency mining

Cryptocurrency mining means the action 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 very strong machine is required. Exactly, the GPU is better for this purpose, because they have more cores available. Cryptocurrency mining farms usually consist of tens and hundreds of graphic cards to conduct their activity effectively. Such systems are not usable for “usual” purposes, like gaming or browsing the Web. Crooks 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

  • 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 Diagscap.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, Diagscap.exe virus makes your system overloaded. It is unable to run your applications anymore, as all CPU power is consumed by a malware. That malware does not care for your needs, all it pays attention to is generating profits on you. Even if you are patient, and you waited until web browser is open, you will likely struggle with extremely sluggish efficiency. Pages can open for years, any type of logins will take about a minute – just a nightmare for a person that works online.

    “Visible” damage is not a single negative activity coin miners do to your system. Diagscap.exe coin miner likewise deals damage to your OS. To perform all malicious operations 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 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 PC recovery.

    Hardware effects of coin miner activity

    Besides slowing down your computer, running at peak level for a long period of time can trigger damage to your machine as well as raise power bills. PC components are created to easily deal with high load, but they can do so only when they are in a good shape.

    Tiny and well-protected CPU fan is not very easy to crack. Meanwhile, graphic cards have big and easy-to-access fans, which can be easily broke if touched while running, for example, by the user much before the virus injection. Malfunctioning cooling system, together with the very high load caused by Diagscap.exe miner can easily lead to graphic card failure3. Video cards are also prone to have fast wearing when used for cryptocurrency mining. It is likely an unwanted case when your GPU’s performance decreases on 20-30% just after several weeks of being exploited in such a way.

    How did I get Diagscap.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 malevolent programs through “major” malware. Adware often functions as a carrier for Diagscap.exe malware injection: it shows you the banners, which have a link to malware downloading. Yes, this abstract “malware” may belong to any kind – an additional adware, spyware, rogue or backdoor. However, the statistics say that around 30% of all malware spread with the malicious banners are coin miners – and Diagscap.exe is right among them.

    Unwanted banners adware

    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 suspicious website as a part of a program. People that spread hacked versions of popular programs (which do not demand the license key) have small chances to make money. Hence, there is a huge lure to include malware to the final package of the hacked app and receive a coin for every installation. Prior to blaming these people for hacking and malware spreading, ask yourself – is it alright to avoid buying the program in such a way? 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 computer.

    How to remove the Diagscap.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 requires using special program. Appropriate anti-malware program must have high efficiency at scanning and be lightweight – in order to make no problems with usage also on weak computers. Furthermore, it is better to have proactive protection in your protection solution – to halt the virus even before it starts. Microsoft Defender lacks these functions for various factors. That’s why I’d suggest you to use a third-party anti-malware program for that reason. GridinSoft Anti-Malware is a superb choice that fits all of the mentioned features.4

    Prior to the malware removal, it is important to boot your Windows into Safe Mode with Networking. Since Diagscap.exe miner takes a lot of processor power, it is needed to stop 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 applications, just like the majority of non-crucial Windows components, are not started with the system start. That gives you the ability to clean the PC without dealing with high CPU usage of the coin miner.
