Besides CPU usage, some of the coin miners also make use of GPU power for their tasks. In that case, you will probably struggle even to see the mouse cursor moving – GPU is often utilized on 100%. It is not as critical as processor for system work, so Bumperww.exe coin miner viruses do not waste time on trifles and use all of it. It sometimes may cause bad results.

Shortly about cryptocurrency mining

Crypto mining term means the action 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 strong computer is needed. 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 GPUs to conduct their activity effectively. Such computer systems are not usable for “normal” purposes, like gaming or web browsing. Crooks who make profit via this coin miner use someones’ hardware instead, even if they are used for the regular activity.2

List of the typical coin miner symptoms

  • Microsoft Defender is stopped;
  • CPU and GPU is loaded at 80-90% exactly after the system start
  • Cooling fans are running at high speed and create a lot of noise
  • A single process in Task Manager consumes all CPU and GPU power

    “Visible” damage is not a solitary negative activity coin miners do to your personal computer. Bumperww.exe coin miner likewise deals damage to your OS. To execute all malevolent functions properly, it wrecks 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 load of new entries – they are added by this trojan miner to connect your PC to a malicious mining network. All these adjustments shall be gone back to the initial state in the process of PC recovery.

    Hardware effects of coin miner activity

    Besides making your computer slow, running at peak power for long times can trigger damage to your machine as well as increase electricity costs. Hardware elements are designed to easily get along with high load, but they can do so only in case when they are in a good shape.

    Small and well-protected processor fan is not very easy to broke. Meanwhile, graphic cards have large and easy-to-access rotors, which can be easily cracked if touched while running, for instance, by the user much before the malware injection. Malfunctioning cooling system, together with the unusually high load caused by Bumperww.exe can easily lead to graphic card failure3. Video cards are also prone to have fast wearing when utilized for cryptocurrency mining. It is surely a bad situation when the performance of your GPU decreases on 20-30% only after 1-2 weeks of being used in such a way.

    How did I get Bumperww.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 “severe” viruses. Adware often acts as a carrier for Bumperww.exe malware injection: it demonstrates you the banners, which have a link to malware downloading. Yes, this abstract “malware” may belong to any type – an additional adware, spyware, rogue or backdoor. But the statistics say that approximately 30% of all malware spread with the malicious banners are coin miners – and Bumperww.exe is just one of them.4

    The example of malicious banners you can see in the Internet

    One more way you could get this item on your computer is by downloading it from the dubious site as a part of a program. Users who spread hacked versions of well-known programs (which do not require the license key) have small chances to earn money. Hence, there is a very big lure to include malware to the final package of the hacked application and acquire a coin for each setup. Before blaming these individuals for hacking and also malware distribution, ask yourself – is it OK to avoid buying the program in this manner? It is more affordable to pay $20-$30 at once than to pay a much greater figure for antivirus software and new parts for your desktop.

    How to remove the Bumperww.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 needs using specific tool. Proper anti-malware program should have high capability at scanning and be lightweight – in order to create no problems with usage also on weak PCs. Additionally, it is better to have on-run security in your security tool – to prevent the virus even before it launches. Microsoft Defender does not have 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 perfect choice that fits each of the discussed qualities.5

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

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