This virus doesn’t pay attention to the fact that you may need to use your system for other tasks – it will always use over 80% of your CPU power.
Chrosha.exe – Very high CPU as well as GPU usage
Besides CPU consumption, some of the coin miners also utilize GPU power for their operations. In that case, you will likely struggle also to see the mouse cursor moving – GPU is usually utilized on 100%.

Shortly about cryptocurrency mining
Cryptocurrency mining means the activity of calculating the transaction block hash. That is a basic element of anything based on the blockchain technology. Since this action takes a lot of calculations, a high-end desktop is needed. Exactly, the video card is better for this purpose, because they have more cores available. Cryptocurrency mining farms usually consist of tens and hundreds of graphic cards to conduct their activity effectively. Such computer systems are not usable for “normal” purposes, like gaming or web browsing. Fraudsters who gain money via this coin miner use someones’ PCs instead, even if they are used for the regular activity.

All these changes are about to be thrown back to the initial state in the process of system recovery.
Hardware effects of coin miner activity
Besides making your PC slow, performing at peak power for a long period of time may trigger damage to your machine as well as raise power costs. Hardware components are created to easily deal with high load, but they can do so only in case when they are in a good shape.
Little and well-protected CPU fan is quite hard to damage. 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 really high load caused by Chrosha.exe can easily lead to graphic card failure. GPUs are also prone to have increased wearing when used for cryptocurrency mining. It is surely an unwanted situation when your GPU’s performance plunges 20-30% only after 1-2 weeks of being exploited in such a way.
How did I get Chrosha.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 the most widespread malicious programs among “severe” malware. Adware sometimes serves as a carrier for Chrosha.exe malware injection: it shows you the banners, which include a link to malware downloading. Yes, this abstract “malware” may belong to any kind – an additional adware, spyware, rogue or backdoor. But the statistics show that about 30% of all viruses spread through the malevolent banners are coin miners – and Chrosha.exe is right one of them.
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 web page as a part of a program. People that spread hacked versions of popular programs (which do not need the license key) have small chances to earn money. For this reason, there is a huge lure to add in malware to the final package of the hacked application and acquire a coin for every setup. Prior to blaming these guys for hacking and also malware spreading, ask yourself – is it alright 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.
How to remove the Chrosha.exe miner from my PC?
The best way to get rid of this coin miner virus is to use anti-malware software
Booting the PC into Safe Mode with Networking
Press the Start button, then choose Power, and click on Reboot while holding the Shift key on the keyboard.
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 PC is in Safe Mode, all third-party programs, just like the majority of non-critical Windows components, are not launched with the system start. That gives you the ability to clean the system without dealing with high CPU usage of the coin miner.
