What is Wup process?

Wup is a malicious process created by coin miner virus

As I have pointed out before, Wup is a coin miner trojan. The names of the executive file can be different, but the impacts are usually the same. Since coin miners aim at cryptocurrency mining, they use all possible hardware power of your personal computer to run this operation. This malware doesn’t pay attention to the fact that you probably need to use your computer for other activities – it will always use over 80% of your CPU power.

Wup Windows Process

Wup – Really high CPU/GPU use

Besides CPU usage, some of the coin miners also make use of GPU power for their operations. In that instance, you will struggle even to see the mouse cursor moving – GPU is often utilized on 100%. It is not as vital as CPU for system work, so Wup coin miner viruses don’t waste time on trifles and utilize it all. It sometimes can cause unhappy effects.

Shortly about cryptocurrency mining

Cryptocurrency mining term means the activity of calculating the transaction block hash. That is a integral part of anything based on the blockchain technology. Since this operation takes a lot of calculations, a very powerful machine is required. Exactly, the GPU is better for this task, because they have more cores available. Cryptocurrency mining farms are usually constructed of dozens of video cards to conduct their activity effectively. Such systems are not usable for “usual” purposes, like gaming or browsing the Web. Fraudsters 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

  • 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 Wup miner?

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

    First off, Wup virus makes your system overloaded. It is unable to run your applications anymore, since all CPU power is used by a malware. That malware does not care for your necessities, all it focuses on is generating income on you. Even if you are patient, and you waited until browser is open, you will likely suffer from extremely slow performance. Pages can open up for years, any sort of logins will take about a minute – just a horror story for a person who does a job online.

    “Visible” damage is not a single unpleasant thing coin miners perform to your PC. Wup coin miner likewise deals damage to your OS. To conduct all malevolent functions effectively, it wrecks the protection features of your system. You will likely see your Microsoft Defender disabled – malware halts it to prevent detection. If you check the HOSTS file, you will likely see a ton of new entries – they are added by this trojan miner to connect your PC to a malicious mining network. All these changes shall be gone back to the initial state in the process of system recovery.

    Hardware effects of coin miner activity

    Besides slowing down your computer, running at peak power for long times can trigger damage to your machine and raise electricity costs. PC components are designed to easily deal with high load, but they can do so only when they are in a good shape.

    Tiny and well-protected CPU cooling system is not very easy to damage. Meanwhile, graphic cards have large and easy-to-access fans, which can be easily cracked if affected while working, for instance, by the user much earlier before the malware injection. Malfunctioning cooling system, together with the really high load caused by Wup can easily lead to graphic card failure3. GPUs are also prone to have fast wearing when utilized for cryptocurrency mining. It is surely an unwanted situation when your GPU’s performance plunges 20-30% just after several weeks of being used in such a way.

    How did I get Wup 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 prevalent malevolent programs among “severe” viruses. Adware frequently functions as a carrier for Wup malware infiltration: it demonstrates you the banners, which contain a link to malware downloading. Sure, this abstract “malware” may belong to any kind – an additional adware, spyware, rogue or backdoor. But the statistics say that approximately 30% of all malware spread with the malicious banners are coin miners – and Wup is right with them.4

    Unwanted banners adware

    The example of malicious banners you can see in the Internet

    One more way you could get this item on your PC is by downloading it from the untrustworthy website 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 get paid. Therefore, there is a very big lure to include malware to the final package of the hacked application and acquire a coin for each setup. Prior to criticizing these guys for hacking and also malware distribution, ask yourself – is it okay to avoid paying for the program in such a way? It is more affordable 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 Wup miner from my PC?

    The best way to get rid of this coin miner virus is to use anti-malware software

    Eliminating such a virus requires the use of special software. Appropriate anti-malware program must have high efficiency at scanning and be lightweight – in order to make no problems with utilization even on weak PCs. In addition, it is recommended to have proactive security in your security tool – 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 perfect option that fits each of the discussed qualities.5

    Before the malware removal, it is important to reboot your operating system into Safe Mode with Networking. Since Wup miner takes a lot of CPU 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 PC is in Safe Mode, all third-party applications, along with the majority of non-critical system components, are not launched with the system start. That gives you the ability to clean the system without dealing with high processor usage of the coin miner.
