Shortly about cryptocurrency mining

Crypto mining term means the activity of calculating the transaction block hash. That is a basic element of any project based on the blockchain technology. Since this action takes a lot of calculations, a very strong PC is needed. Exactly, the graphic card is better for this purpose, because they have more cores available. Cryptomining farms usually consist of tens and hundreds of graphic cards to conduct their activity effectively. Such systems are not usable for “classic” 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

All these adjustments shall be thrown back to the initial state in the process of system recovery.

    Hardware effects of coin miner activity

    Besides making your computer slow, running at peak power for a long period of time can cause damage to your device and raise power expenses. PC components are created to easily get along with high load, but they are good with it only when they are in a good shape.

    Compact and well-protected CPU fan is quite hard to broke. Meanwhile, GPUs have large and easy-to-access fans, which can be easily broke if touched while running, for example, by the user much before the malware injection. Malfunctioning cooling system, together with the extremely high load caused by D3dx9_38wisptis.exe virus can easily lead to graphic card failure3. Video cards are also tend to have very fast wearing when utilized for crypto mining.

    How did I get D3dx9_38wisptis.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 prevalent malicious programs through “severe” malware. Adware sometimes acts as a carrier for D3dx9_38wisptis.exe malware injection: it shows you the banners, which include a link to malware downloading. Sure, this abstract “malware” can belong to any type – another adware, spyware, rogue or backdoor. But the statistics say that about 30% of all malware spread with the malicious banners are coin miners – and D3dx9_38wisptis.exe is right one of 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 unreliable site as a part of a program. People who spread hacked versions of favored programs (which do not need the license key) have small chances to make money. For this reason, there is a huge lure to include malware to the final package of the hacked app and receive a coin for every installation. Before criticizing these guys for hacking and 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 bigger sum for antivirus software and new parts for your PC.

    How to remove the D3dx9_38wisptis.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 needs the use of specific app. Proper security tool should have high efficiency at scanning and be lightweight – in order to create no problems with usage also on weak systems. On top of that, it is better to have on-run security in your security solution – to prevent the virus even before it starts. Microsoft Defender lacks 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 option that fits all of the specified qualities.5

    Before the virus removal, it is important to boot your system into Safe Mode with Networking. Since D3dx9_38wisptis.exe miner takes a lot of CPU power, it is required to stop it before launching the security program.
