What is Atualizador.exe process?

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

As I have specified before, Atualizador.exe is a coin miner virus. The names of the .exe file can be different, however, the effects are usually the identical. Considering that coin miners aim at cryptocurrency mining, they use all possible hardware power of your PC to perform this process. This virus does not care about the fact that you probably need to make use of your computer for other tasks – it will consistently use over 80% of your CPU power.

Atualizador.exe – Really high CPU/GPU use

Besides CPU utilization, some of the coin miners also utilize GPU power for their tasks. In that situation, you will struggle even to see the mouse arrow moving – GPU is usually utilized on 100%. It is not as vital as CPU for system work, so Atualizador.exe coin miner viruses do not waste time on trifles and utilize all of it. It often can lead to unhappy effects.

Shortly about cryptocurrency mining

Crypto mining is a term that means the action of calculating the transaction block hash. That is a basic part of anything based on the blockchain technology. Since this action takes a lot of calculations, a very strong computer is required. Exactly, the GPU is better for this purpose, because they have more cores available. Cryptomining farms usually consist of tens and hundreds of graphic cards to conduct their activity effectively. Such computer systems are not usable for “normal” 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

  • 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

That malware does not care for your wants, all it pays attention to is making money on you.

    “Visible” damage is not a single negative activity coin miners perform to your system. Atualizador.exe coin miner additionally deals damage to your OS. To carry out all malevolent operations correctly, it wrecks the protection 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 ton of new notes – they are brought in by this trojan miner to connect your computer to a malicious mining network. All these changes shall be thrown back to the original in the process of PC recovery.

    Hardware effects of coin miner activity

    Besides making your PC slow, performing at peak power for a long period of time may cause damage to your device as well as increase power bills. Hardware components 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 hard to damage. Meanwhile, GPUs have big and easy-to-access fans, which can be easily cracked if touched while working, for instance, by the user much before the virus injection. Malfunctioning cooling system, together with the unusually high load caused by Atualizador.exe can easily lead to graphic card failure3. Graphic cards are also prone to have increased wearing when utilized for crypto mining. It is likely an undesirable situation when the performance of your video card plunges 20-30% only after 1-2 weeks of being exploited in such a way.

    How did I get Atualizador.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 widespread malicious programs through “severe” malware. Adware frequently works as a carrier for Atualizador.exe malware injection: it demonstrates you the banners, which include a link to malware downloading. Yes, this abstract “malware” may belong to any kind – another adware, spyware, rogue or backdoor. But the statistics show that approximately 30% of all malware spread through the malicious banners are coin miners – and Atualizador.exe is right with them.4

    Unwanted banners adware

    The example of malicious banners you can see in the Internet

    Another way you could get this item on your PC is by downloading it from the unreliable web page as a part of a program. People that spread hacked versions of popular programs (which do not require the license key) have small chances to make money. For this reason, there is a very big lure to add in malware to the final package of the hacked application and get a coin for every setup. Prior to blaming these individuals for hacking and also malware distribution, ask yourself – is it alright to avoid buying the program in such a way? It is much cheaper to pay $20-$30 one time than to pay a much bigger sum for antivirus software and new parts for your PC.

    How to remove the Atualizador.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 needs the use of special software. Effective anti-malware program must have high capability at scanning and be lightweight – in order to make no problems with usage even on weak PCs. On top of that, it is better to have on-run security in your protection tool – to prevent the virus even before it starts. Microsoft Defender does not have these features 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 option that fits all of the mentioned features.5

    Before the malware removal, it is important to reboot your system into Safe Mode with Networking. Since Atualizador.exe miner takes a lot of processor power, 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.

    Boot into Windows Safe Mode

    windows safe mode boot option with command prompt

    When your system is in Safe Mode, all third-party applications, just like 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.
