Ilasm.exe executable file is related to a harmful application that can accurately be recognized as a coin miner trojan. That malware type uses your hardware to mine cryptocurrencies, primarily – Monero or DarkCoin1. It makes your system roughly unusable as a result of high CPU usage.
What is Ilasm.exe process?
Ilasm.exe is a malicious process created by coin miner virus
As I have pointed out previously, Ilasm.exe is a coin miner trojan. The names of the .exe file can be different, however, the impacts are generally the same. Since coin miners focus on cryptocurrency mining, they utilize all possible hardware power of your personal computer to run this process. This malware doesn’t pay attention to the fact that you probably need to use your PC for other activities – it will consistently consume over 80% of your CPU power.
Ilasm.exe – Very high CPU/GPU usage
Besides CPU usage, some of the coin miners additionally utilize GPU power for their operations. In that case, you will struggle also to see the mouse arrow moving – GPU is often used on 100%. It is not as crucial as processor for system work, so Ilasm.exe coin miner viruses do not waste time on trifles and use all of it. It sometimes can cause sad effects.
Shortly about cryptocurrency mining
Crypto mining is a term that means the activity 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 video card is better for this purpose, because they have more cores available. Cryptomining farms are usually constructed of dozens of graphic cards to complete their task efficiently. Such systems are not usable for “normal” purposes, like gaming or browsing the Web. Crooks who make profit via this coin miner use someones’ hardware instead, even if they are used for the regular activity.2

“Visible” harm is not a single bad activity coin miners perform to your personal computer. Ilasm.exe coin miner likewise deals damage to your operating system. To conduct all malevolent operations successfully, it ruins the security features of your system. You will likely see your Microsoft Defender disabled – malware halts it to avoid detection. If you open the HOSTS file, you will likely see a load of new entries – they are added by this coin miner to connect your system to a malicious cryptomining network. All these changes are about to be thrown back to the initial state in the process of PC recovery.
Hardware effects of coin miner activity
Besides slowing down your PC, running at peak level for long times may cause damage to your device and increase power costs. PC components are created to easily deal with high load, but they are good with it only in case when they are in a good shape.
Little and covered processor cooling system is not very easy to broke. Meanwhile, GPUs have large and easy-to-access fans, which can be easily cracked if affected while running, for example, by the user much before the coin-miner injection. Malfunctioning cooling system, together with the really high load caused by Ilasm.exe can easily lead to graphic processing unit failure3. Video cards 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 decreases on 20-30% just after 1-2 weeks of being used in such a way.
How did I get Ilasm.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 prevalent malevolent programs among “major” malware. Adware often works as a carrier for Ilasm.exe malware injection: it shows you the banners, which include a link to malware downloading. Sure, this abstract “malware” may belong to any type – another adware, spyware, rogue or backdoor. But the statistics say that around 30% of all malware spread through the malevolent banners are coin miners – and Ilasm.exe is right among them.
The example of malicious banners you can see in the Internet
An additional way you could get this item on your PC is by downloading it from the unreliable web page 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 earn money. For this reason, there is a huge lure to add in malware to the final package of the hacked application and get a coin for every installation. Prior to blaming these individuals for hacking and malware distribution, ask yourself – is it OK to avoid purchasing the program in such a way? It is much cheaper to pay $20-$30 at once than to pay a much greater sum for antivirus software and new parts for your PC.
How to remove the Ilasm.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 computer is in Safe Mode, all third-party software, just like the majority of non-critical operating system components, are not launched with the system start. That allows you to clean the computer without dealing with high processor usage of the coin miner.
