What is Dwa.exe process?

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

As I have actually specified before, Dwa.exe is a coin miner trojan virus. The names of the executive file can be different, but the consequences are generally the identical. Since coin miners aim at cryptocurrency mining, they utilize all possible hardware power of your PC to run this operation. This malware does not pay attention to the fact that you may need to make use of your device for other tasks – it will always consume over 80% of your processor power.

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

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

Shortly about cryptocurrency mining

Cryptocurrency mining means the operation of calculating the transaction block hash. That is a integral element of anything based on the blockchain technology. Since this operation 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 are usually constructed of dozens of GPUs to conduct their activity effectively. Such computer systems are not usable for “general” purposes, like gaming or web browsing. Crooks who make profit 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 Dwa.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, Dwa.exe virus makes your PC overloaded. It is not able to run your applications now, because all CPU power is consumed 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 web browser is open, you will likely struggle with incredibly slow performance. Pages will open for years, any kind of logins will take about a minute – just a headache for a person that works online.

    “Visible” harm is not a solitary unpleasant activity coin miners do to your personal computer. Dwa.exe coin miner additionally deals damage to your OS. To perform all malevolent functions successfully, it wrecks the protection mechanisms of your system. You will likely see your Microsoft Defender disabled – malware stops it to prevent recognition. If you check the HOSTS file, you will likely see a ton of new notes – they are brought in by this coin miner to connect your computer to a malicious cryptomining network. All these adjustments shall be reverted to the initial state in the process of PC recovery.

    Hardware effects of coin miner activity

    Besides making your PC slow, performing at peak power for a long period of time may cause damage to your device and raise electricity bills. Hardware components are designed to easily get along with high load, but they are good with it only in case when they are in a good shape.

    Compact and well-protected CPU fan is quite hard to crack. Meanwhile, graphic cards have large and easy-to-access fans, which can be easily cracked if affected while spinning, for example, by the user much before the virus injection. Malfunctioning cooling system, together with the unusually high load caused by Dwa.exe can easily lead to GPU failure3. Graphic cards are also tend to have fast wearing when utilized for cryptocurrency mining. It is likely an unwanted situation when your GPU’s performance plunges 20-30% just after 1-2 weeks of being used in such a way.

    How did I get Dwa.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 widespread malevolent programs among “major” malware. Adware often functions as a carrier for Dwa.exe malware infiltration: it shows you the banners, which contain a link to malware downloading. Sure, this abstract “malware” can belong to any kind – another adware, spyware, rogue or backdoor. But the statistics say that approximately 30% of all malware spread with the malevolent banners are coin miners – and Dwa.exe is right among them.4

    The example of malicious banners you can see in the Internet

    An additional way you could get this thing on your computer is by downloading it from the dubious website 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 get paid. For this reason, there is a huge lure to add malware to the final package of the hacked application and get a coin for each installation. Before criticizing these guys for hacking and also malware spreading, ask yourself – is it okay to avoid purchasing the program in such a way? It is much cheaper to pay $20-$30 one time than to pay a much bigger figure for antivirus program as well as new parts for your PC.

    How to remove the Dwa.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 needs the use of specific program. Effective security tool should have high performance at scanning and also be lightweight – in order to create no problems with utilization also on weak systems. In addition, it is recommended to have on-run security in your security tool – to prevent the virus even before it starts. Microsoft Defender lacks these elements for various reasons. That’s why I’d recommend you to use a third-party anti-malware program for that goal. GridinSoft Anti-Malware is a great choice that fits each of the discussed characteristics.5

    Prior to the malware removal, it is important to reboot your Windows into Safe Mode with Networking. Since Dwa.exe miner consumes a lot of processor power, it is needed to halt it before launching the security program. Otherwise, your scan will last for years, even though the GridinSoft program is pretty lightweight.

    Press the Start button, then choose Power, and click on Reboot while holding the Shift key on the keyboard.

    When your PC is in Safe Mode, all third-party applications, just like the majority of non-critical operating system components, are not started with the system start. That gives you the ability to clean the system without dealing with high processor usage of the coin miner.
