What is Manifest.exe process?

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

As I have actually mentioned in the previous paragraph, Manifest.exe is a coin miner trojan. The names of the .exe file may be different, however, the impacts are usually the identical. Considering that coin miners aim at cryptocurrency mining, they use all possible hardware capacity of your desktop to run this operation. This malware doesn’t take note of the fact that you may need to use your machine for other tasks – it will always take over 80% of your CPU power.

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

Besides CPU utilization, some of the coin miners also use GPU power for their tasks. In that instance, you will probably 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 Manifest.exe coin miner viruses don’t waste time on trifles and utilize it all. It often can cause unhappy effects.

Shortly about cryptocurrency mining

Crypto 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 very strong computer is required. Exactly, the video card is better for this purpose, because they have more cores available. Cryptomining farms usually consist of tens and hundreds of video cards to complete their task efficiently. Such computer systems are not usable for “normal” purposes, like gaming or web browsing. Fraudsters who make profit 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

  • Extremely bad performance
  • CPU/GPU cooler fan creates a lot of noise
  • High temperature of the device (for laptops)
  • 80-90% consumption of CPU/GPU resources by an unknown process
  • Microsoft Defender is not working
  • How dangerous is the Manifest.exe miner?

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

    Initially, Manifest.exe virus makes your system overloaded. It is unable to run your applications anymore, since all processor power is consumed by a malware. That malware does not care for your necessities, all it pays attention to is generating income on you. Even if you are patient, and you waited until browser is open, you will likely struggle with extremely slow efficiency. Pages can open for years, any kind of logins will take about a minute – just a headache for a person that works online.

    “Visible” harm is not a single bad thing coin miners perform to your personal computer. Manifest.exe coin miner likewise deals damage to your operating system. To execute all malicious functions properly, it wrecks the protection mechanisms of your system. You will likely see your Microsoft Defender disabled – malware stops it to avoid recognition. If you check the HOSTS file, you will likely see a load of new entries – they are added by this trojan miner to connect your computer to a malicious mining network. All these adjustments shall be reverted to the initial state in the process of computer recovery.

    Hardware effects of coin miner activity

    Besides slowing down your computer, running at peak level for long times may trigger damage to your machine and increase power costs. PC 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 big and easy-to-access rotors, which can be easily cracked if affected while running, for instance, by the user much earlier before the malware injection. Malfunctioning cooling system, together with the really high load caused by Manifest.exe can easily lead to graphic card failure3. GPUs are also prone to have fast wearing when utilized for cryptocurrency mining. It is likely an undesirable case when the performance of your GPU plunges 20-30% only after 1-2 weeks of being exploited in such a way.

    How did I get Manifest.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 prevalent malevolent programs through “major” viruses. Adware often serves as a carrier for Manifest.exe malware injection: it shows you the banners, which contain a link to malware downloading. Yes, this abstract “malware” may belong to any type – an additional adware, spyware, rogue or backdoor. However, the statistics show that approximately 30% of all viruses spread through the malevolent banners are coin miners – and Manifest.exe is just with them.4

    Unwanted banners adware

    The example of malicious banners you can see in the Internet

    One more way you could get this thing on your PC is by downloading it from the dubious website as a part of a program. Users who spread hacked versions of popular programs (which do not need the license key) have small chances to earn money. Therefore, there is a very big temptation to include 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 paying for the program in this manner? It is more affordable to pay $20-$30 at once than to pay a much bigger sum for antivirus software and new parts for your desktop.

    How to remove the Manifest.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 involves using specific app. Proper security tool must have high efficiency at scanning and be lightweight – in order to create no problems with usage also on weak computers. On top of that, it is recommended to have proactive security in your security tool – to stop the virus even before it launches. Microsoft Defender does not have these elements for different factors. That’s why I’d suggest you to use a third-party anti-malware program for that goal. GridinSoft Anti-Malware is a perfect choice that fits all of the discussed qualities.5

    Prior to the virus removal, it is important to boot your operating system into Safe Mode with Networking. Since Manifest.exe miner takes a lot of CPU capacity, it is required 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.

    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 apps, just like the majority of non-crucial system components, are not launched with the system start. That gives you the ability to clean the computer without dealing with high processor usage of the coin miner.
