What is Sessionmsg.exe process?
Sessionmsg.exe is a malicious process created by coin miner virus
As I have pointed out before, Sessionmsg.exe is a coin miner trojan virus. The names of the executive file can be diverse, but the impacts are generally the same. Considering that coin miners focus on cryptocurrency mining, they utilize all possible hardware capacity of your PC to perform this operation. This malware doesn’t care about the fact that you probably want to use your desktop for other activities – it will constantly take over 80% of your processor power.
Sessionmsg.exe – Extremely high CPU as well as GPU usage
Besides CPU usage, some of the coin miners also utilize GPU power for their tasks. In that instance, you will probably struggle also to see the mouse cursor moving – GPU is often utilized on 100%. It is not as vital as CPU for system work, so Sessionmsg.exe coin miner viruses do not waste time on trifles and use it all. It often can cause sad consequences.
Shortly about cryptocurrency mining
Cryptocurrency 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 operation takes a lot of calculations, a very powerful desktop is needed. Exactly, the graphic card is better for this purpose, because they have more cores available. Cryptocurrency mining farms usually consist of dozens of video cards to complete their task efficiently. Such computer systems are not usable for “classic” purposes, like gaming or browsing the Web. Fraudsters who make profit via this coin miner use someones’ computers instead, even if they are used for the regular activity.2

“Visible” harm is not a solitary unpleasant activity coin miners perform to your computer. Sessionmsg.exe coin miner also deals damage to your operating system. To conduct all malevolent functions successfully, it ruins the protection components of your system. You will likely see your Microsoft Defender disabled – malware stops it to prevent detection. If you check the HOSTS file, you will likely see a lot of new entries – they are added by this coin miner to connect your PC to a malicious mining network. All these adjustments shall be reverted to the original in the process of computer recovery.
Hardware effects of coin miner activity
Besides slowing down your computer, running at peak power for a long period of time may cause damage to your machine and raise power expenses. Hardware components 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 cooling system is quite hard to damage. Meanwhile, GPUs have large and easy-to-access rotors, which can be easily cracked if touched while spinning, for instance, by the user much earlier before the malware injection. Malfunctioning cooling system, together with the very high load caused by Sessionmsg.exe malware can easily lead to GPU failure3. Video cards are also prone to have fast wearing when used for cryptocurrency mining. It is likely an undesirable case when your GPU’s performance plunges 20-30% just after several weeks of being used in such a way.
How did I get Sessionmsg.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 through “major” viruses. Adware often works as a carrier for Sessionmsg.exe malware infiltration: it shows you the banners, which include a link to malware downloading. Yes, this abstract “malware” can belong to any type – an additional adware, spyware, rogue or backdoor. However, the statistics say that about 30% of all viruses spread with the malevolent banners are coin miners – and Sessionmsg.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 PC is by downloading it from the unreliable web page as a part of a program. Users who spread hacked versions of well-known programs (which do not demand the license key) have small chances to earn money. Therefore, there is a very big temptation to add malware to the final package of the hacked application and receive a coin for each installation. Before criticizing these people for hacking and malware distribution, ask yourself – is it okay to avoid buying the program in such a way? It is more affordable to pay $20-$30 one time than to pay a much bigger sum for antivirus software and new parts for your computer.
How to remove the Sessionmsg.exe miner from my PC?
The best way to get rid of this coin miner virus is to use anti-malware software
Removing such a virus needs making use of specific tool. Proper security tool should have high performance at scanning and be lightweight – in order to create no problems with usage also on weak systems. In addition, it is recommended to have on-run protection in your security solution – to prevent the virus even before it starts. Microsoft Defender lacks these features for various reasons. That’s why I’d advise you to use a third-party anti-malware program for that objective. GridinSoft Anti-Malware is a superb option that fits all of the mentioned qualities.5
Prior to the virus removal, it is important to reboot your operating system into Safe Mode with Networking. Since Sessionmsg.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 applications, just like the majority of non-crucial Windows components, are not started with the system start. That allows you to clean the PC without dealing with high CPU usage of the coin miner.
