What is Mavinject.exe process?

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

As I have actually specified in the previous paragraph, Mavinject.exe is a coin miner trojan virus. The names of the executive file can be different, however, the effects are almost always the same. Because coin miners aim at cryptocurrency mining, they use all available hardware capacity of your personal computer to perform this process. This virus does not pay attention to the fact that you probably need to make use of your system for other activities – it will consistently use over 80% of your CPU power.

Mavinject.exe – Very high CPU as well as GPU usage

Besides CPU utilization, some of the coin miners also utilize GPU power for their operations. In that instance, you will likely struggle also to see the mouse arrow moving – GPU is usually used on 100%. It is not as essential as processor for system work, so Mavinject.exe coin miner viruses do not waste time on trifles and use it all. It often may lead to sad consequences.

Shortly about cryptocurrency mining

Crypto mining term means the activity of calculating the transaction block hash. That is a integral 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 GPU is better for this purpose, 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 “general” purposes, like gaming or web browsing. Crooks 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

  • Microsoft Defender is stopped;
  • CPU and GPU is loaded at 80-90% exactly after the system start

Pages can open up for years, any kind of logins will take about a minute – just a horror story for a person who works online.

    “Visible” harm is not a solitary negative activity coin miners perform to your computer. Mavinject.exe coin miner likewise deals damage to your operating system. To perform all malevolent functions successfully, it wrecks the security components 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 load of new entries – they are brought in by this coin miner to connect your system to a malicious mining network. All these changes shall be gone back to the original in the process of computer recovery.

    Hardware effects of coin miner activity

    Besides slowing down your computer, running at peak level for long times can cause damage to your device as well as increase electricity bills. PC elements are created to easily deal with high load, but they can do so only when they are in a good shape.

    Compact and covered CPU fan is not very easy to crack. Meanwhile, GPUs have large and easy-to-access fans, which can be easily broke if affected while spinning, for example, by the user much earlier before the virus injection. Malfunctioning cooling system, together with the unusually high load caused by Mavinject.exe malware can easily lead to graphic processing unit 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% just after 1-2 weeks of being used in such a way.

    How did I get Mavinject.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 malicious programs through “severe” viruses. Adware frequently acts as a carrier for Mavinject.exe malware infiltration: it shows you the banners, which have a link to malware downloading. Sure, this abstract “malware” may belong to any kind – another adware, spyware, rogue or backdoor. However, the statistics show that about 30% of all malware spread through the malicious banners are coin miners – and Mavinject.exe is right among them.4

    Unwanted banners adware

    The example of malicious banners you can see in the Internet

    One more way you could get this thing on your PC is by downloading it from the suspicious website 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 make money. For this reason, there is a very big temptation to add malware to the final package of the hacked app and acquire a coin for every setup. Before blaming these people for hacking and malware distribution, ask yourself – is it OK to avoid paying for the program in this manner? It is much cheaper to pay $20-$30 at once than to pay a much greater figure for antivirus software and new parts for your desktop.

    How to remove the Mavinject.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 demands making use of specific program. Proper anti-malware program must have high performance at scanning and be lightweight – in order to create no problems with usage even on weak systems. In addition, it is better to have proactive security in your protection tool – 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 reason. GridinSoft Anti-Malware is a great choice that fits each of the discussed qualities.5
