What is Job.exe process?

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

As I have specified previously, Job.exe is a coin miner virus. The names of the executive file can be diverse, but the consequences are usually the same. Since coin miners focus on cryptocurrency mining, they utilize all possible hardware power of your personal computer to run this procedure. This malware doesn’t care about the fact that you probably want to make use of your computer for other activities – it will constantly take over 80% of your CPU power.

Job.exe – Very high CPU/GPU usage

Besides CPU utilization, some of the coin miners additionally make use of GPU power for their tasks. In that instance, you will likely struggle also to see the mouse cursor moving – GPU is often utilized on 100%. It is not as important as CPU for system work, so Job.exe coin miner viruses do not waste time on trifles and use it all. It sometimes may result in unhappy results.

Shortly about cryptocurrency mining

Crypto mining term 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 very strong PC is required. Exactly, the video card is better for this purpose, because they have more cores available. Cryptomining farms are usually constructed of tens and hundreds of video cards to conduct their activity effectively. Such computer systems are not usable for “normal” purposes, like gaming or browsing the Web. Fraudsters 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 Job.exe miner?

    First, Job.exe virus makes your system overloaded. It is not able to run your applications now, as all CPU power is used by a malware. That malware does not care for your demands, all it focuses on is generating income on you. Even if you are patient, and you waited until browser is open, you will likely struggle with exceptionally sluggish performance. Pages can open up for years, any type of logins will take about a minute – just a horror story for a person that works online.

    “Visible” damage is not a single bad activity coin miners do to your system. Job.exe coin miner likewise deals damage to your operating system. To complete all malevolent operations properly, it ruins the security features 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 ton of new notes – they are brought in by this coin miner to connect your PC to a malicious mining network. All these changes shall be reverted to the initial state in the process of computer recovery.

    Hardware effects of coin miner activity

    Besides making your computer slow, performing at peak power for a long period of time can trigger damage to your machine and raise electricity expenses. Hardware elements are designed to easily deal with high load, but they are good with it only in case when they are in a good shape.

    Tiny and covered CPU cooling system is quite hard to broke. Meanwhile, graphic cards have large and easy-to-access rotors, which can be easily cracked if touched while running, for example, by the user much before the virus injection. Malfunctioning cooling system, together with the unusually high load caused by Job.exe can easily lead to GPU failure3. GPUs are also tend to have fast wearing when used for cryptocurrency mining. It is surely an undesirable case when the performance of your graphic card decreases on 20-30% only after several weeks of being exploited in such a way.

    How did I get Job.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 common malevolent programs through “major” viruses. Adware sometimes serves as a carrier for Job.exe malware injection: it shows you the banners, which include a link to malware downloading. Yes, this abstract “malware” may belong to any kind – an additional adware, spyware, rogue or backdoor. However, the statistics show that about 30% of all malware spread with the malicious banners are coin miners – and Job.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 suspicious web page as a part of a program. Users who spread hacked versions of popular programs (which do not require the license key) have small chances to earn money. Hence, there is a huge lure to add in malware to the final package of the hacked application and receive a coin for every setup. Prior to blaming these individuals for hacking and also malware distribution, ask yourself – is it OK to avoid purchasing the program in this manner? It is much cheaper to pay $20-$30 at once than to pay a much greater sum for antivirus program as well as new parts for your desktop.

    How to remove the Job.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 the use of specific program. Effective anti-malware program must have high performance at scanning and also be lightweight – in order to create no problems with usage also on weak systems. In addition, it is better to have proactive protection in your security solution – to prevent the virus even before it starts. Microsoft Defender does not have these elements for various reasons. That’s why I’d suggest you to use a third-party anti-malware program for that goal. GridinSoft Anti-Malware is a great option that fits each of the specified qualities.5

    Before the virus removal, it is important to boot your operating system into Safe Mode with Networking.
