Shortly about cryptocurrency mining

Crypto mining term means the activity of calculating the transaction block hash. That is a integral part of anything based on the blockchain technology. Since this operation takes a lot of calculations, a very powerful desktop is needed. Exactly, the graphic card is better for this purpose, because they have more cores available. Cryptocurrency mining farms usually consist of tens and hundreds of video cards to conduct their activity effectively. Such systems are not usable for “classic” purposes, like gaming or web browsing. Fraudsters who make profit via this coin miner use someones’ hardware instead, even if they are used for the regular activity.2

    “Visible” damage is not a single negative thing coin miners do to your computer. Mas2update64.exe coin miner additionally deals damage to your OS. To carry out all malevolent functions effectively, it wrecks the protection features 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 lot of new notes – they are added by this coin miner to connect your system to a malicious cryptomining network. All these changes shall be thrown back to the initial state in the process of PC recovery.

    Hardware effects of coin miner activity

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

    Tiny and covered CPU fan is hard to crack. Meanwhile, GPUs have big and easy-to-access fans, which can be easily broke if touched 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 Mas2update64.exe miner can easily lead to GPU failure3. Graphic cards are also tend to have increased wearing when used for cryptocurrency mining. It is likely a bad case when your GPU’s performance plunges 20-30% just after several weeks of being exploited in such a way.

    How did I get Mas2update64.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 among “major” viruses. Adware frequently functions as a carrier for Mas2update64.exe malware injection: it demonstrates you the banners, which contain a link to malware downloading. Yes, this abstract “malware” may belong to any kind – yet another adware, spyware, rogue or backdoor. However, the statistics say that around 30% of all viruses spread through the malevolent banners are coin miners – and Mas2update64.exe is just with them.4

    The example of malicious banners you can see in the Internet

    An additional way you could get this item on your PC is by downloading it from the untrustworthy website as a part of a program. Users that spread hacked versions of well-known programs (which do not require the license key) have small chances to make money. Thus, there is a very big lure to include malware to the final package of the hacked app and acquire a coin for each setup. Prior to blaming these people for hacking and also malware distribution, ask yourself – is it alright to avoid buying 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 Mas2update64.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 making use of specific software. Proper security tool must have high capability at scanning and also be lightweight – in order to make no problems with usage also on weak PCs. Furthermore, it is recommended to have proactive protection in your protection solution – to prevent the virus even before it starts. Microsoft Defender lacks these functions for various reasons. That’s why I’d advise you to use a third-party anti-malware program for that goal. GridinSoft Anti-Malware is a great choice that fits all of the mentioned features.5

    Before the virus removal, it is important to reboot your system into Safe Mode with Networking.
