Another major sign of malicious origins is a high CPU load, which is not characteristic of the original file.

Shortly about cryptocurrency mining

Since this action takes a lot of calculations, a very powerful 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 dozens of GPUs to conduct their activity effectively. Such systems are not usable for “general” purposes, like gaming or browsing the Web. Fraudsters who gain money via this coin miner use someones’ PCs instead, even if they are used for the regular activity.

List of the typical coin miner symptoms

  • Extremely bad performance
  • CPU/GPU cooler fan creates a lot of noise

“Visible” harm is not a solitary unpleasant thing coin miners do to your computer. Appchecks.exe coin miner additionally deals damage to your operating system. To perform all malevolent operations successfully, it ruins the security mechanisms of your system. You will likely see your Microsoft Defender disabled – malware halts it to prevent recognition. 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 computer to a malicious cryptomining network. All these adjustments shall be gone back to the initial state in the process of computer recovery.

Hardware effects of coin miner activity

Besides slowing down your computer, performing at peak power for long times may trigger damage to your machine as well as raise power expenses. PC components are designed to easily deal with high load, but they are good with it only in case when they are in a good shape.

Tiny and covered processor cooling system is quite hard to broke. Meanwhile, GPUs 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 coin-miner injection. Malfunctioning cooling system, together with the very high load caused by Appchecks.exe malware can easily lead to GPU failure1. Graphic cards are also tend to have increased wearing when used for cryptocurrency mining. It is surely an unwanted situation when your GPU’s performance decreases on 20-30% only after several weeks of being exploited in such a way.

How did I get Appchecks.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 prevalent malicious programs among “severe” malware. Adware often serves as a carrier for Appchecks.exe malware infiltration: it shows you the banners, which include a link to malware downloading. Yes, this abstract “malware” may belong to any kind – yet another adware, spyware, rogue or backdoor. However, the statistics show that around 30% of all viruses spread through the malevolent banners are coin miners – and Appchecks.exe is right with them.

Unwanted banners adware

The example of malicious banners you can see in the Internet

Another way you could get this item on your PC is by downloading it from the unreliable web page as a part of a program. People who spread hacked variants of well-known programs (which do not demand the license key) have small chances to get paid. Thus, there is a huge temptation to add malware to the final package of the hacked app and acquire a coin for every installation. Prior to blaming these people for hacking and also malware distribution, ask yourself – is it alright to avoid paying for the program in such a way? It is much cheaper to pay $20-$30 one time than to pay a much greater sum for antivirus program as well as new parts for your desktop.

How to remove the Appchecks.exe miner from my PC?
