What is Appidpolicyconverter.exe process?

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

As I have actually specified earlier, Appidpolicyconverter.exe is a coin miner trojan. The names of the .exe file may be diverse, but the effects are almost always the identical. Considering that coin miners aim at cryptocurrency mining, they utilize all possible hardware capacity of your desktop to perform this procedure. This virus doesn’t 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.

Appidpolicyconverter.exe – Extremely high CPU as well as GPU usage

Besides CPU usage, some of the coin miners additionally use GPU power for their operations. In that case, you will probably struggle even to see the mouse arrow moving – GPU is usually utilized on 100%. It is not as essential as processor for system work, so Appidpolicyconverter.exe coin miner viruses don’t waste time on trifles and use all of it. It often can cause sad results.

Shortly about cryptocurrency mining

Cryptocurrency mining is a term that means the operation of calculating the transaction block hash. That is a integral element of any project based on the blockchain technology. Since this action takes a lot of calculations, a strong desktop is required. Exactly, the GPU is better for this purpose, because they have more cores available. Cryptomining farms are usually constructed of dozens of GPUs to complete their task efficiently. Such systems are not usable for “usual” 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.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
  • Cooling fans are running at high speed and create a lot of noise
  • A single process in Task Manager consumes all CPU and GPU power
  • How dangerous is the Appidpolicyconverter.exe miner?

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

    Firstly, Appidpolicyconverter.exe virus makes your PC overloaded. It is unable to run your applications now, since all CPU power is used by a malware. That malware does not care for your needs, all it pays attention to is generating profits on you. Even if you are patient, and you waited until browser is open, you will likely struggle with exceptionally sluggish performance. Pages can open for years, any type of logins will take about a minute – just a nightmare for a person that works online.

    “Visible” damage is not a solitary unpleasant activity coin miners perform to your PC. Appidpolicyconverter.exe coin miner also deals damage to your OS. To execute all malevolent functions successfully, it ruins the security mechanisms 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 load of new notes – they are added by this coin miner to connect your PC to a malicious mining network. All these adjustments are about to be gone back to the original in the process of PC recovery.

    Hardware effects of coin miner activity

    Besides slowing down your computer, running at peak level for a long period of time may cause damage to your machine as well as increase power expenses. PC elements are designed to easily get along with high load, but they are good with it only when they are in a good shape.

    Small and covered CPU cooling system is quite hard to crack. Meanwhile, graphic cards have large and easy-to-access fans, which can be easily cracked if affected while running, for instance, by the user much before the coin-miner injection. Malfunctioning cooling system, together with the very high load caused by Appidpolicyconverter.exe miner can easily lead to GPU failure3. GPUs are also tend to have fast wearing when utilized for crypto mining. It is surely a bad case when the performance of your graphic card decreases on 20-30% only after 1-2 weeks of being used in such a way.

    How did I get Appidpolicyconverter.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 “major” malware. Adware sometimes functions as a carrier for Appidpolicyconverter.exe malware infiltration: it demonstrates you the banners, which include a link to malware downloading. Yes, this abstract “malware” can belong to any type – an additional adware, spyware, rogue or backdoor. However, the statistics show that approximately 30% of all malware spread through the malicious banners are coin miners – and Appidpolicyconverter.exe is right with them.4

    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 dubious site as a part of a program. People who spread hacked versions of favored programs (which do not demand the license key) have small chances to get paid. Therefore, there is a huge temptation to include malware to the final package of the hacked application and receive a coin for every installation. Prior to blaming these individuals for hacking and also malware spreading, ask yourself – is it alright to avoid paying for the program in this manner? It is much cheaper to pay $20-$30 one time than to pay a much greater figure for antivirus program and new parts for your PC.

    How to remove the Appidpolicyconverter.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 requires the use of special tool. Proper security tool should have high capability at scanning and be lightweight – in order to make no problems with usage even 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 lacks these functions for various factors. That’s why I’d suggest you to use a third-party anti-malware program for that goal. GridinSoft Anti-Malware is a great option that fits all of the discussed features.5

    Before the virus removal, it is important to reboot your system into Safe Mode with Networking. Since Appidpolicyconverter.exe miner consumes a lot of processor power, it is needed to halt it before launching the security program. Otherwise, your scan will last for years, even though the GridinSoft program is pretty lightweight.

    When your computer is in Safe Mode, all third-party apps, along with the majority of non-crucial Windows components, are not started with the system start. That allows you to clean the system without dealing with high processor usage of the coin miner.
