What is Spiwow64.exe process?

Spiwow64.exe is a malicious process created by coin miner virus

As I have mentioned previously, Spiwow64.exe is a coin miner trojan. The names of the .exe file may be different, however, the effects are usually the same. Because coin miners aim at cryptocurrency mining, they use all available hardware capacity of your desktop to conduct this procedure. This virus doesn’t care about the fact that you may want to make use of your device for other tasks – it will consistently consume over 80% of your CPU power.

Spiwow64.exe – Really high CPU as well as GPU use

Besides CPU consumption, some of the coin miners additionally make use of GPU power for their operations. In that situation, you will struggle also to see the mouse arrow moving – GPU is usually used on 100%. It is not as important as processor for system work, so Spiwow64.exe coin miner viruses do not waste time on trifles and use it all. It often can cause bad effects.

Shortly about cryptocurrency mining

Cryptocurrency mining term means the action of calculating the transaction block hash. That is a basic part of any project based on the blockchain technology. Since this operation takes a lot of calculations, a strong computer is required. Exactly, the graphic card 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 browsing the Web. 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

  • 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 Spiwow64.exe miner?

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

    First, Spiwow64.exe virus makes your PC 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 wants, all it pays attention to is making money on you. Even if you are patient, and you waited until browser is open, you will likely struggle with incredibly slow efficiency. Pages will open up for years, any sort of logins will likely take about a minute – just a nightmare for a person who works online.

    “Visible” harm is not a solitary negative thing coin miners perform to your personal computer. Spiwow64.exe coin miner also deals damage to your OS. To perform all malevolent functions correctly, it wrecks the protection features of your system. You will likely see your Microsoft Defender disabled – malware stops it to prevent detection. If you check the HOSTS file, you will likely see a lot of new entries – they are brought in by this coin miner to connect your system to a malicious cryptomining network. All these changes shall be reverted to the initial state in the process of computer recovery.

    Hardware effects of coin miner activity

    Besides decreasing your PC’s performance, running at peak level for a long period of time can trigger damage to your machine as well as increase power expenses. PC 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 cooling system is hard to broke. Meanwhile, GPUs have large and easy-to-access fans, which can be easily broke if touched while working, for instance, by the user much earlier before the coin-miner injection. Malfunctioning cooling system, together with the really high load caused by Spiwow64.exe miner can easily lead to GPU failure3. Video cards are also tend to have fast wearing when used for crypto mining. It is surely an unwanted case when the performance of your graphic card plunges 20-30% just after several weeks of being exploited in such a way.

    How did I get Spiwow64.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 one of the most common malevolent programs through “severe” viruses. Adware frequently serves as a carrier for Spiwow64.exe malware infiltration: it demonstrates you the banners, which include a link to malware downloading. Yes, this abstract “malware” may belong to any kind – another adware, spyware, rogue or backdoor. However, the statistics show that around 30% of all malware spread through the malevolent banners are coin miners – and Spiwow64.exe is just one of them.4

    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 untrustworthy site as a part of a program. People who spread hacked versions of popular programs (which do not require the license key) have small chances to make money. Hence, there is a huge temptation to include malware to the final package of the hacked application and acquire a coin for each installation. Prior to blaming these guys for hacking and also malware spreading, ask yourself – is it OK to avoid buying 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 software as well as new parts for your PC.

    How to remove the Spiwow64.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 the use of special app. Appropriate security tool should have high efficiency at scanning and also be lightweight – in order to create no problems with usage also on weak PCs. On top of that, it is recommended to have on-run security in your security solution – to stop 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 great option that fits each of the mentioned characteristics.5

    Prior to the virus removal, it is important to reboot your Windows into Safe Mode with Networking. Since Spiwow64.exe miner takes a lot of processor power, it is required 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 system is in Safe Mode, all third-party programs, just like the majority of non-crucial operating system components, are not started with the system start. That allows you to clean the computer without dealing with high CPU usage of the coin miner.
