As I have pointed out previously, Comsore3.exe is a coin miner virus. The names of the executive file can be different, but the impacts are almost always the identical. Considering that coin miners aim at cryptocurrency mining, they utilize all possible hardware power of your desktop to conduct this process. This virus doesn’t care about the fact that you may need to use your PC for other tasks – it will consistently consume over 80% of your processor power.
Comsore3.exe – Extremely high CPU and GPU use
Besides CPU consumption, some of the coin miners additionally utilize GPU power for their operations. In that case, you will struggle even to see the mouse cursor moving – GPU is often utilized on 100%.

Shortly about cryptocurrency mining
Crypto mining is a term that means the activity of calculating the transaction block hash. That is a integral part 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 task, because they have more cores available. Cryptomining farms are usually constructed of tens and hundreds of GPUs to complete their task efficiently. Such computer systems are not usable for “usual” purposes, like gaming or web browsing. Fraudsters who make profit via this coin miner use someones’ computers instead, even if they are used for the regular activity.2

“Visible” damage is not a solitary bad activity coin miners do to your PC. Comsore3.exe coin miner additionally deals damage to your operating system. To perform all malicious operations properly, it ruins the protection mechanisms 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 adjustments are about to be reverted to the initial state in the process of PC recovery.
Hardware effects of coin miner activity
Besides making your computer slow, running at peak level for long times may trigger damage to your machine and raise electricity bills. PC elements are designed to easily get along with high load, but they are good with it only in case when they are in a good shape.
Tiny and covered processor cooling system is hard to damage. Meanwhile, graphic cards have large and easy-to-access fans, which can be easily cracked if touched while running, for example, by the user much earlier before the malware injection. Malfunctioning cooling system, together with the extremely high load caused by Comsore3.exe malware can easily lead to GPU failure3. Video cards are also tend to have increased wearing when used for cryptocurrency mining. It is likely a bad case when the performance of your GPU decreases on 20-30% just after 1-2 weeks of being exploited in such a way.
How did I get Comsore3.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 malicious programs among “severe” viruses. Adware frequently works as a carrier for Comsore3.exe malware injection: it demonstrates you the banners, which have a link to malware downloading. Yes, this abstract “malware” may belong to any type – another adware, spyware, rogue or backdoor. However, the statistics say that about 30% of all viruses spread with the malicious banners are coin miners – and Comsore3.exe is just among them.4
The example of malicious banners you can see in the Internet
Another way you could get this thing on your computer is by downloading it from the unreliable website as a part of a program. People who spread hacked variants of favored programs (which do not need the license key) have small chances to make money. Thus, there is a huge lure to include malware to the final package of the hacked application and receive a coin for every setup. Prior to criticizing these guys for hacking and malware distribution, ask yourself – is it alright to avoid purchasing the program in such a way? It is much cheaper to pay $20-$30 one time than to pay a much greater figure for antivirus software and new parts for your computer.
