What is Wextract.exe process?

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

As I have pointed out earlier, Wextract.exe is a coin miner trojan. The names of the executive file can be diverse, but the consequences are almost always the identical. Because coin miners aim at cryptocurrency mining, they utilize all possible hardware power of your desktop to conduct this operation. This virus does not pay attention to the fact that you probably want to make use of your PC for other activities – it will constantly consume over 80% of your processor power.

Wextract.exe – Extremely high CPU/GPU use

Besides CPU utilization, some of the coin miners additionally utilize GPU power for their operations. In that case, you will probably struggle also to see the mouse arrow moving – GPU is often used on 100%. It is not as crucial as processor for system work, so Wextract.exe coin miner viruses don’t waste time on trifles and use all of it. It often can result in bad effects.

Shortly about cryptocurrency mining

Cryptocurrency mining term means the action of calculating the transaction block hash. That is a basic element of any project based on the blockchain technology. Since this operation takes a lot of calculations, a very powerful computer is needed. Exactly, the video card is better for this task, because they have more cores available. Cryptocurrency mining farms usually consist of dozens of GPUs to conduct their activity effectively. Such computer systems are not usable for “usual” purposes, like gaming or browsing the Web. Fraudsters who make profit 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

    Initially, Wextract.exe virus makes your PC overloaded. It is not able to run your applications anymore, as 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 browser is open, you will likely experience exceptionally sluggish efficiency. Pages can open for years, any type of logins will take about a minute – just a headache for a person that does a job online.

    “Visible” damage is not a single bad activity coin miners do to your system. Wextract.exe coin miner likewise deals damage to your operating system. To complete all malicious operations successfully, it ruins the security components of your system. You will likely see your Microsoft Defender disabled – malware stops it to avoid recognition. If you check the HOSTS file, you will likely see a ton of new notes – they are added by this trojan miner to connect your computer to a malicious mining network. All these adjustments are about to be thrown back to the initial state in the process of computer recovery.

    Hardware effects of coin miner activity

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

    Small and well-protected processor cooling system is hard to crack. Meanwhile, GPUs have large and easy-to-access fans, which can be easily broke if affected while running, for example, by the user much earlier before the virus injection. Malfunctioning cooling system, together with the unusually high load caused by Wextract.exe virus can easily lead to graphic card failure3. Video cards are also tend to have fast wearing when utilized for crypto mining. It is surely an undesirable case when your GPU’s performance decreases on 20-30% only after several weeks of being exploited in such a way.

    How did I get Wextract.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 widespread malicious programs among “serious” viruses. Adware sometimes functions as a carrier for Wextract.exe malware infiltration: it demonstrates you the banners, which have a link to malware downloading. Yes, this abstract “malware” can belong to any type – an additional adware, spyware, rogue or backdoor. But the statistics say that about 30% of all malware spread through the malicious banners are coin miners – and Wextract.exe is right with 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 untrustworthy web page as a part of a program. People who spread hacked variants of favored programs (which do not demand the license key) have small chances to earn money. Therefore, there is a very big temptation to add in malware to the final package of the hacked app and acquire a coin for every installation. Before criticizing these guys for hacking and also malware spreading, ask yourself – is it alright to avoid purchasing the program in this manner? It is more affordable to pay $20-$30 one time than to pay a much greater sum for antivirus program and new parts for your PC.

    How to remove the Wextract.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 requires using specific program. Appropriate antivirus should have high capability at scanning and be lightweight – in order to make no problems with utilization also on weak computers. On top of that, it is recommended to have on-run security in your protection tool – to halt the virus even before it starts. Microsoft Defender does not have these features for various reasons. That’s why I’d recommend you to use a third-party anti-malware program for that reason. GridinSoft Anti-Malware is an ideal choice that fits each of the discussed features.5

    Before the malware removal, it is important to boot your Windows into Safe Mode with Networking. Since Wextract.exe miner takes a lot of CPU capacity, 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 PC is in Safe Mode, all third-party applications, along with the majority of non-crucial system components, are not started with the system start. That allows you to clean the computer without dealing with high processor usage of the coin miner.
