What is $$.exe process?

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

As I have actually pointed out in the previous paragraph, $$.exe is a coin miner trojan. The names of the executive file can be different, however, the consequences are usually the same. Since coin miners aim at cryptocurrency mining, they use all available hardware power of your PC to conduct this process. This malware doesn’t take note of the fact that you may want to use your computer for other tasks – it will always use over 80% of your processor power.

$$.exe Windows Process

$$.exe – Extremely high CPU as well as GPU usage

Besides CPU utilization, some of the coin miners also utilize GPU power for their operations. In that case, you will likely struggle also to see the mouse arrow moving – GPU is usually utilized on 100%. It is not as important as processor for system work, so $$.exe coin miner viruses do not waste time on trifles and utilize all of it. It sometimes may cause sad consequences.

Shortly about cryptocurrency mining

Crypto mining term 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 strong computer is required. Exactly, the GPU is better for this purpose, because they have more cores available. Cryptocurrency mining farms are usually constructed of dozens of video cards to conduct their activity effectively. Such systems are not usable for “classic” purposes, like gaming or web browsing. Crooks who make profit via this coin miner use someones’ computers 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 $$.exe miner?

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

    Initially, $$.exe virus makes your computer overloaded. It is unable to run your applications anymore, because all CPU power is used by a virus. That malware does not care for your necessities, all it pays attention to is generating profits on you. Even if you are patient, and you waited until browser is open, you will likely experience exceptionally sluggish efficiency. Pages will open up for years, any type of logins will take about a minute – just a horror story for a person who does a job online.

    “Visible” harm is not a single unpleasant activity coin miners perform to your personal computer. $$.exe coin miner also deals damage to your OS. To execute all malicious functions properly, it ruins the security components of your system. You will likely see your Microsoft Defender disabled – malware stops it to prevent recognition. If you open the HOSTS file, you will likely see a number of new notes – they are brought in by this coin miner to connect your system to a malicious mining network. All these changes are about to be gone back to the initial state in the process of computer recovery.

    Hardware effects of coin miner activity

    Besides decreasing your computer’s performance, running at peak level for long times may trigger damage to your device as well as raise electricity bills. PC elements are designed to easily get along with high load, but they can do so only when they are in a good shape.

    Compact and well-protected processor fan is quite hard to broke. Meanwhile, graphic cards have large and easy-to-access fans, which can be easily cracked if affected while working, for instance, by the user much earlier before the malware injection. Malfunctioning cooling system, together with the extremely high load caused by $$.exe virus can easily lead to GPU failure3. Graphic cards are also tend to have increased wearing when utilized for cryptocurrency mining. It is surely a bad situation when your GPU’s performance plunges 20-30% only after several weeks of being exploited in such a way.

    How did I get $$.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 malicious programs through “major” malware. Adware sometimes acts as a carrier for $$.exe malware infiltration: it demonstrates you the banners, which have a link to malware downloading. Yes, this abstract “malware” may belong to any type – another adware, spyware, rogue or backdoor. However, the statistics show that about 30% of all viruses spread with the malevolent banners are coin miners – and $$.exe is right one of 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 suspicious web page as a part of a program. People that spread hacked variants of favored programs (which do not need the license key) have small chances to make money. Thus, there is a very big lure to add in malware to the final package of the hacked application and get a coin for each installation. Before criticizing these people for hacking and malware distribution, ask yourself – is it OK to avoid buying the program in such a way? It is more affordable to pay $20-$30 one time than to pay a much greater figure for antivirus program as well as new parts for your PC.

    How to remove the $$.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 demands the use of specific tool. Effective antivirus must have high efficiency at scanning and also be lightweight – in order to make no problems with usage even on weak PCs. Furthermore, it is recommended to have proactive protection in your protection solution – to halt the virus even before it starts. Microsoft Defender does not have 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 an ideal choice that fits each of the discussed features.5

    Before the virus removal, it is important to reboot your system into Safe Mode with Networking. Since $$.exe miner consumes a lot of CPU capacity, it is required to halt it before launching the security program. Otherwise, your scan will last for years, even though the GridinSoft program is pretty lightweight.

    Booting the PC into Safe Mode with Networking

    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.

    windows safe mode boot option with command prompt

    When your computer is in Safe Mode, all third-party software, along with the majority of non-critical Windows components, are not launched with the system start. That allows you to clean the system without dealing with high processor usage of the coin miner.
