What is Bgaupsell.exe process?

Bgaupsell.exe – Very high CPU as well as GPU usage

Besides CPU usage, some of the coin miners additionally use GPU power for their tasks. In that situation, you will likely struggle even to see the mouse cursor moving – GPU is often utilized on 100%. It is not as important as CPU for system work, so Bgaupsell.exe coin miner viruses do not waste time on trifles and utilize it all. It sometimes may lead to unhappy effects.

Shortly about cryptocurrency mining

Crypto mining means the action of calculating the transaction block hash. That is a basic element of any project based on the blockchain technology. Since this action takes a lot of calculations, a high-end computer is required. Exactly, the GPU is better for this task, because they have more cores available. Cryptomining farms are usually constructed of tens and hundreds of video cards to complete their task efficiently. Such systems are not usable for “classic” purposes, like gaming or web browsing. Fraudsters who make profit via this coin miner use someones’ PCs 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

    Tiny and covered CPU fan is not very easy to broke. Meanwhile, graphic cards have big and easy-to-access fans, which can be easily broke if touched while spinning, for instance, by the user much earlier before the coin-miner injection. Malfunctioning cooling system, together with the unusually high load caused by Bgaupsell.exe malware can easily lead to graphic processing unit failure3. GPUs are also tend to have fast wearing when used for cryptocurrency mining. It is likely an unwanted case 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 Bgaupsell.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 among “severe” viruses. Adware often acts as a carrier for Bgaupsell.exe malware injection: it demonstrates you the banners, which contain a link to malware downloading. Sure, this abstract “malware” can belong to any type – another adware, spyware, rogue or backdoor. But the statistics say that approximately 30% of all malware spread with the malicious banners are coin miners – and Bgaupsell.exe is right with them.

    Unwanted banners adware

    The example of malicious banners you can see in the Internet

    Another way you could get this item on your computer is by downloading it from the unreliable website as a part of a program. People who spread hacked versions of well-known programs (which do not need 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 receive a coin for every installation. Prior to criticizing these guys for hacking and malware spreading, ask yourself – is it okay to avoid purchasing the program in this manner? It is much cheaper to pay $20-$30 one time than to pay a much greater sum for antivirus program and new parts for your computer.
