What is Bootsect.exe process?

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

As I have actually specified in the introduction, Bootsect.exe is a coin miner virus. The names of the .exe file may be different, but the consequences are usually the identical. Since coin miners focus on cryptocurrency mining, they use all possible hardware capacity of your personal computer to run this process. This malware doesn’t take note of the fact that you may need to make use of your device for other tasks – it will continuously take over 80% of your processor power.

Besides CPU usage, some of the coin miners also make use of GPU power for their tasks. In that case, you will struggle even to see the mouse cursor moving – GPU is usually utilized on 100%. It is not as important as CPU for system work, so Bootsect.exe coin miner viruses don’t waste time on trifles and utilize all of it. It sometimes can lead to sad consequences.

Shortly about cryptocurrency mining

Crypto mining means the action of calculating the transaction block hash. That is a integral element of anything based on the blockchain technology. Since this action takes a lot of calculations, a very strong computer is required. Exactly, the video card is better for this purpose, because they have more cores available. Cryptomining farms are usually constructed of tens and hundreds of video cards to conduct their activity effectively. Such systems are not usable for “usual” purposes, like gaming or web browsing. Crooks who gain money via this coin miner use someones’ PCs instead, even if they are used for the regular activity.2

    “Visible” harm is not a single unpleasant activity coin miners do to your system. Bootsect.exe coin miner additionally deals damage to your operating system.

All these adjustments shall be thrown back to the original in the process of computer recovery.

    Hardware effects of coin miner activity

    Besides making your PC slow, performing at peak power for long times may cause damage to your machine as well as raise power bills. PC elements are created to easily deal with high load, but they can do so only in case when they are in a good shape.

    Tiny and well-protected CPU cooling system is hard to crack. Meanwhile, graphic cards have large and easy-to-access rotors, which can be easily broke if touched while spinning, for instance, by the user much earlier before the virus injection. Malfunctioning cooling system, together with the unusually high load caused by Bootsect.exe miner can easily lead to GPU failure3. Video cards are also prone to have increased wearing when used for crypto mining. It is surely an undesirable case when your GPU’s performance plunges 20-30% only after 1-2 weeks of being used in such a way.

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

    Unwanted banners adware

    The example of malicious banners you can see in the Internet

    One more way you could get this item on your PC is by downloading it from the unreliable website as a part of a program. People that spread hacked versions of popular programs (which do not demand the license key) have small chances to earn money. Therefore, there is a huge temptation to add in malware to the final package of the hacked app and get a coin for every setup. Before criticizing these people for hacking and also malware distribution, ask yourself – is it OK to avoid purchasing the program in this manner? It is more affordable to pay $20-$30 one time than to pay a much greater figure for antivirus program as well as new parts for your desktop.

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

Effective anti-malware program should have high efficiency at scanning and be lightweight – in order to create no problems with usage also on weak PCs. Furthermore, it is recommended to have proactive protection in your security tool – to stop the virus even before it launches. Microsoft Defender does not have these features for various reasons.
