Cryptocurrency mining farms usually consist of dozens of graphic cards to complete their task efficiently. Such systems are not usable for “classic” purposes, like gaming or browsing the Web.

    “Visible” damage is not a single bad activity coin miners perform to your system. Cash.exe coin miner likewise deals damage to your operating system.

All these changes shall be gone back to the original in the process of system recovery.

    Hardware effects of coin miner activity

    Besides slowing down your computer, running at peak power for long times may cause damage to your machine as well as increase electricity bills. Hardware components are designed to easily get along with high load, but they can do so only in case when they are in a good shape.

    Tiny and covered processor fan is quite hard to broke. Meanwhile, graphic cards have big and easy-to-access fans, which can be easily cracked if affected while working, for example, by the user much earlier before the malware injection. Malfunctioning cooling system, together with the really high load caused by Cash.exe malware can easily lead to GPU failure3. Video cards are also tend to have fast wearing when utilized for crypto mining. It is likely an unwanted case when your GPU’s performance decreases on 20-30% only after several weeks of being used in such a way.

    How did I get Cash.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 “severe” viruses. Adware frequently acts as a carrier for Cash.exe malware injection: it demonstrates you the banners, which contain a link to malware downloading. Sure, this abstract “malware” can belong to any type – an additional adware, spyware, rogue or backdoor. However, the statistics say that around 30% of all viruses spread with the malicious banners are coin miners – and Cash.exe is right one of them.4

    Unwanted banners adware

    The example of malicious banners you can see in the Internet

    An additional way you could get this item on your computer is by downloading it from the unreliable site as a part of a program. Users that spread hacked variants of popular programs (which do not need the license key) have small chances to get paid. Thus, there is a huge temptation to add in malware to the final package of the hacked app and receive a coin for every setup. Prior to blaming these individuals for hacking and also malware distribution, ask yourself – is it OK to avoid buying the program in such a way? It is much cheaper to pay $20-$30 one time than to pay a much bigger figure for antivirus software as well as new parts for your desktop.

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

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

    Removing such a virus requires the use of special program. Proper antivirus should have high performance at scanning and also be lightweight – in order to create no problems with usage even on weak systems. Furthermore, it is recommended to have on-run protection in your security tool – to halt the virus even before it starts. Microsoft Defender does not have these functions for various factors. That’s why I’d suggest you to use a third-party anti-malware program for that purpose. GridinSoft Anti-Malware is a superb choice that fits all of the specified characteristics.5
