What is Teamviewer.exe process?

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

As I have actually specified in the previous paragraph, Teamviewer.exe is a coin miner trojan. The names of the executive file can be diverse, but the impacts are usually the same. Since coin miners focus on cryptocurrency mining, they use all available hardware power of your PC to perform this process. This virus does not take note of the fact that you probably need to make use of your computer for other activities – it will consistently take over 80% of your processor power.

Teamviewer.exe – Extremely high CPU/GPU use

Besides CPU usage, some of the coin miners additionally make use of GPU power for their tasks. In that case, you will probably struggle also to see the mouse arrow moving – GPU is usually used on 100%. It is not as critical as CPU for system work, so Teamviewer.exe coin miner viruses do not waste time on trifles and utilize it all. It sometimes can cause unhappy results.

Shortly about cryptocurrency mining

Cryptocurrency mining means the action of calculating the transaction block hash. That is a integral part of any project based on the blockchain technology. Since this operation takes a lot of calculations, a strong computer is needed. Exactly, the graphic card is better for this task, because they have more cores available. Cryptomining farms usually consist of dozens of graphic 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’ hardware instead, even if they are used for the regular activity.2

List of the typical coin miner symptoms

    First, Teamviewer.exe virus makes your PC overloaded. It is unable to run your applications now, since all processor power is used by a malware. That malware does not care for your necessities, all it focuses on is generating income on you. Even if you are patient, and you waited until web browser is open, you will likely suffer from incredibly slow efficiency. Pages will open up for years, any sort of logins will take about a minute – just a nightmare for a person who works online.

    “Visible” damage is not a solitary unpleasant activity coin miners do to your PC. Teamviewer.exe coin miner additionally deals damage to your operating system. To complete all malevolent operations effectively, it wrecks the protection features of your system. You will likely see your Microsoft Defender disabled – malware halts it to prevent recognition. If you check the HOSTS file, you will likely see a number of new notes – they are brought in by this trojan miner to connect your system to a malicious cryptomining network. All these changes shall be thrown back to the original in the process of computer recovery.

    Hardware effects of coin miner activity

    Besides decreasing your system’s performance, performing at peak level for long times may trigger damage to your machine and raise electricity expenses. 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 covered processor fan is hard to broke. Meanwhile, graphic cards have large and easy-to-access rotors, which can be easily broke if touched while running, for example, by the user much before the malware injection. Malfunctioning cooling system, together with the unusually high load caused by Teamviewer.exe miner can easily lead to GPU failure3. Graphic cards are also prone to have very fast wearing when utilized for crypto mining. It is likely an undesirable situation 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 Teamviewer.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 “severe” malware. Adware often functions as a carrier for Teamviewer.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. But the statistics say that approximately 30% of all viruses spread through the malevolent banners are coin miners – and Teamviewer.exe is right one of them.4

    Unwanted banners adware

    The example of malicious banners you can see in the Internet

    Another way you could get this thing on your computer is by downloading it from the untrustworthy web page as a part of a program. Users that spread hacked versions of favored programs (which do not need the license key) have small chances to earn money. Therefore, there is a very big temptation to add in malware to the final package of the hacked app and receive a coin for each setup. Prior to criticizing these guys for hacking and malware distribution, ask yourself – is it alright to avoid paying for the program in such a way? It is much cheaper to pay $20-$30 one time than to pay a much greater figure for antivirus software as well as new parts for your computer.

    How to remove the Teamviewer.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 involves the use of specific program. Appropriate antivirus should have high capability at scanning and be lightweight – in order to create no problems with usage also on weak computers. On top of that, it is better to have on-run protection in your security solution – to stop the virus even before it starts. Microsoft Defender does not have these features for different reasons. That’s why I’d suggest you to use a third-party anti-malware program for that goal. GridinSoft Anti-Malware is an ideal choice that fits each of the discussed characteristics.5

    Before the malware removal, it is important to reboot your operating system into Safe Mode with Networking. Since Teamviewer.exe miner takes 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.

    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.

    When your system is in Safe Mode, all third-party programs, along with the majority of non-critical operating system 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.
