Since this operation takes a lot of calculations, a very powerful PC is needed. Exactly, the graphic card is better for this task, because they have more cores available. Cryptomining farms are usually constructed of dozens of GPUs to complete their task efficiently. Such computer systems are not usable for “normal” 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

    Hardware effects of coin miner activity

    Besides making your computer slow, running at peak power for long times may trigger damage to your device as well as raise electricity bills. PC elements are designed to easily get along with high load, but they are good with it only in case when they are in a good shape.

    Little and well-protected processor fan is quite hard to broke. Meanwhile, GPUs have large and easy-to-access fans, which can be easily broke if touched while spinning, for example, by the user much before the virus injection. Malfunctioning cooling system, together with the really high load caused by Hostupdater.exe virus can easily lead to GPU failure3. Video cards are also prone to have very fast wearing when utilized for crypto mining. It is likely a bad situation when the performance of your graphic card decreases on 20-30% just after 1-2 weeks of being used in such a way.

    How did I get Hostupdater.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 common malevolent programs through “major” malware. Adware frequently acts as a carrier for Hostupdater.exe malware injection: it demonstrates you the banners, which have a link to malware downloading. Sure, this abstract “malware” can belong to any type – yet another adware, spyware, rogue or backdoor. But the statistics say that approximately 30% of all malware spread through the malicious banners are coin miners – and Hostupdater.exe is right one of them.4

    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 untrustworthy web page as a part of a program. Users that spread hacked variants of favored programs (which do not require the license key) have small chances to get paid. Therefore, there is a huge lure to add in malware to the final package of the hacked app and acquire a coin for every setup. Prior to criticizing these individuals for hacking and also malware distribution, ask yourself – is it okay to avoid buying the program in this manner? It is much cheaper to pay $20-$30 at once than to pay a much greater figure for antivirus program as well as new parts for your desktop.

    How to remove the Hostupdater.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 involves making use of specific tool. Proper antivirus must have high efficiency at scanning and be lightweight – in order to make no problems with usage even on weak systems. On top of that, it is recommended to have proactive security in your security tool – to stop the virus even before it launches. Microsoft Defender lacks these elements for different reasons. That’s why I’d suggest you to use a third-party anti-malware program for that goal. GridinSoft Anti-Malware is a perfect option that fits each of the mentioned characteristics.5

    Before the malware removal, it is important to boot your Windows into Safe Mode with Networking. Since Hostupdater.exe miner consumes a lot of CPU capacity, it is required to stop it before launching the security program. Otherwise, your scan will last for years, even though the GridinSoft program is pretty lightweight.

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