Bloom.exe Virus ⛏️ (Coin Miner Trojan) Removal

What is Bloom.exe process?

As I have actually pointed out in the introduction, Bloom.exe is a coin miner trojan. The names of the .exe file may be diverse, however, the effects are generally the same. Because coin miners focus on cryptocurrency mining, they utilize all available hardware capacity of your desktop to run this process. This virus doesn’t take note of the fact that you may want to use your system for other activities – it will always take over 80% of your processor power.

Bloom.exe – Extremely high CPU as well as GPU use

Besides CPU utilization, some of the coin miners additionally make use of GPU power for their tasks. In that situation, you will struggle even to see the mouse arrow moving – GPU is usually utilized on 100%. It is not as critical as processor for system work, so Bloom.exe coin miner viruses don’t waste time on trifles and utilize it all. It often can lead to bad consequences.

Cryptocurrency mining term means the operation of calculating the transaction block hash. That is a integral element of any project based on the blockchain technology. Since this action takes a lot of calculations, a very powerful computer is required. Exactly, the graphic card is better for this task, because they have more cores available. Cryptomining farms are usually constructed of tens and hundreds of graphic cards to conduct their activity effectively. Such computer systems are not usable for “classic” purposes, like gaming or web browsing. Crooks who make profit via this coin miner use someones’ computers instead, even if they are used for the regular activity.²

How dangerous is the Bloom.exe miner?

First off, Bloom.exe malware makes your PC overloaded. It is unable to run your applications now, because all CPU power is used by a malware. That malware does not care for your necessities, all it focuses on is making money on you. Even if you are patient, and you waited until web browser is open, you will likely experience extremely sluggish efficiency. Pages will open for years, any kind of logins will likely take about a minute – just a nightmare for a person that does a job online.

Bloom.exe Technical Summary.

“Visible” damage is not a solitary unpleasant thing coin miners do to your personal computer. Bloom.exe coin miner also deals damage to your operating system. To conduct all malevolent operations properly, it ruins the security components of your system. You will likely see your Microsoft Defender disabled – malware stops it to prevent recognition. If you check the HOSTS file, you will likely see a ton of new entries – they are added by this coin miner to connect your PC to a malicious cryptomining network. All these changes are about to be reverted to the original in the process of system recovery.

Hardware effects of coin miner activity

Besides making your PC slow, running at peak power for long times may trigger damage to your device as well as raise electricity costs. PC components are created to easily get along with high load, but they can do so only when they are in a good shape.

Tiny and covered processor cooling system is not very easy to damage. Meanwhile, graphic cards have big and easy-to-access rotors, which can be easily broke if touched while running, for instance, by the user much earlier before the malware injection. Malfunctioning cooling system, together with the very high load caused by Bloom.exe virus can easily lead to graphic card failure³. GPUs are also tend to have increased wearing when used for crypto mining. It is likely an unwanted case when the performance of your video card plunges 20-30% only after several weeks of being exploited in such a way.

How did I get Bloom.exe coin miner virus?

Coin miners are the most common malicious programs through “severe” viruses. Adware frequently functions as a carrier for Bloom.exe malware injection: it shows you the banners, which have a link to malware downloading. Yes, this abstract “malware” can belong to any type – an additional adware, spyware, rogue or backdoor. However, the statistics say that approximately 30% of all viruses spread through the malicious banners are coin miners – and Bloom.exe is right among them.⁴

The example of malicious banners you can see in the Internet

One more way you could get this thing on your computer is by downloading it from the dubious website as a part of a program. People that spread hacked versions of popular programs (which do not require the license key) have small chances to make money. Thus, there is a very big temptation to add in malware to the final package of the hacked app and get a coin for every installation. Before blaming these individuals for hacking and malware distribution, ask yourself – is it alright to avoid buying the program in this manner? It is more affordable to pay $20-$30 one time than to pay a much bigger sum for antivirus program as well as new parts for your desktop.

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

Eliminating such a virus involves using specific app. Effective antivirus must have high capability at scanning and be lightweight – in order to make no problems with utilization also on weak PCs. Additionally, it is recommended to have on-run security in your protection tool – to prevent the virus even before it launches. Microsoft Defender lacks these functions for different factors. That’s why I’d suggest you to use a third-party anti-malware program for that objective. GridinSoft Anti-Malware is a superb option that fits each of the specified qualities.⁵

Prior to the virus removal, it is important to reboot your operating system into Safe Mode with Networking. Since Bloom.exe miner consumes a lot of processor capacity, it is required to halt it before launching the security program. Otherwise, your scan will last for years, even though the GridinSoft program is pretty lightweight.

Windows will reboot into recovery mode. In that mode, choose Troubleshoot→ Startup Settings→ Safe Mode with Networking. Press the corresponding button on your keyboard to choose that option.

When your system is in Safe Mode, all third-party software, just like the majority of non-critical Windows components, are not started with the system start. That gives you the ability to clean the system without dealing with high CPU usage of the coin miner.
