What is Gallery.exe process?

Gallery.exe is a malicious process created by coin miner virus

As I have mentioned in the introduction, Gallery.exe is a coin miner trojan virus. The names of the .exe file may be diverse, but the impacts are generally the identical. Since coin miners focus on cryptocurrency mining, they use all possible hardware capacity of your PC to run this process. This malware doesn’t pay attention to the fact that you probably want to use your system for other activities – it will consistently consume over 80% of your CPU power.

Gallery.exe Windows Process

Gallery.exe – Really high CPU as well as GPU use

Besides CPU usage, some of the coin miners also utilize GPU power for their operations. In that situation, you will likely struggle also to see the mouse arrow moving – GPU is usually utilized on 100%. It is not as critical as processor for system work, so Gallery.exe coin miner viruses don’t waste time on trifles and use it all. It often may cause bad results.

Shortly about cryptocurrency mining

Cryptocurrency mining means the action of calculating the transaction block hash. That is a integral part of anything based on the blockchain technology. Since this operation takes a lot of calculations, a strong machine is required. Exactly, the GPU is better for this task, because they have more cores available. Cryptocurrency mining farms are usually constructed of dozens of video cards to complete their task efficiently. Such systems are not usable for “classic” purposes, like gaming or web browsing. Crooks who gain money 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
  • How dangerous is the Gallery.exe miner?

    Coin miners does not deal damage to your files. However, they make a lot of unpleasant things with the whole system

    First of all, Gallery.exe malware makes your system overloaded. It is unable to run your applications now, because all CPU power is consumed by a malware. That malware does not care for your demands, all it pays attention to is making money on you. Even if you are patient, and you waited until web browser is open, you will likely suffer from extremely slow performance. Pages can open for years, any sort of logins will take about a minute – just a horror story for a person who does a job online.

    “Visible” harm is not a solitary unpleasant activity coin miners perform to your PC. Gallery.exe coin miner additionally deals damage to your operating system. To execute all malevolent operations effectively, it wrecks the protection mechanisms 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 load of new entries – they are added by this coin miner to connect your PC to a malicious mining network. All these changes are about to be reverted to the initial state in the process of system recovery.

    Hardware effects of coin miner activity

    Besides making your computer slow, performing at peak level for a long period of time may cause damage to your machine as well as increase electricity bills. 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 CPU fan is quite hard to broke. Meanwhile, graphic cards have large and easy-to-access rotors, which can be easily cracked if affected while working, for example, by the user much before the coin-miner injection. Malfunctioning cooling system, together with the unusually high load caused by Gallery.exe can easily lead to GPU failure3. Graphic cards are also tend to have very fast wearing when utilized for cryptocurrency mining. It is surely a bad case when your GPU’s performance decreases on 20-30% only after 1-2 weeks of being used in such a way.

    How did I get Gallery.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 through “severe” malware. Adware sometimes serves as a carrier for Gallery.exe malware infiltration: it shows you the banners, which include a link to malware downloading. Sure, this abstract “malware” can belong to any type – an additional adware, spyware, rogue or backdoor. However, the statistics show that approximately 30% of all viruses spread through the malicious banners are coin miners – and Gallery.exe is right one of them.4

    The example of malicious banners you can see in the Internet

    An additional way you could get this thing on your PC is by downloading it from the dubious 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. For this reason, there is a very big temptation to add malware to the final package of the hacked app and get 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 bigger figure for antivirus software and new parts for your desktop.

    How to remove the Gallery.exe miner from my PC?

    The best way to get rid of this coin miner virus is to use anti-malware software

    Eliminating such a virus needs using specific program. Effective antivirus must have high efficiency at scanning and also be lightweight – in order to make no problems with utilization also on weak PCs. In addition, it is recommended to have proactive security in your security tool – to prevent the virus even before it launches. Microsoft Defender does not have these elements for different reasons. That’s why I’d recommend you to use a third-party anti-malware program for that reason. GridinSoft Anti-Malware is a perfect choice that fits all of the mentioned characteristics.5

    Prior to the virus removal, it is important to reboot your Windows into Safe Mode with Networking. Since Gallery.exe miner consumes a lot of processor power, it is needed to stop it before launching the security program. Otherwise, your scan will last for years, even though the GridinSoft program is pretty lightweight.

    Press the Start button, then choose Power, and click on Reboot while holding the Shift key on the keyboard.

    Boot into Windows Safe Mode

    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, along with the majority of non-critical Windows components, are not launched with the system start. That gives you the ability to clean the PC without dealing with high CPU usage of the coin miner.
