What is Qualityagent64.exe process?

Qualityagent64.exe is a malicious process created by coin miner virus

As I have mentioned before, Qualityagent64.exe is a coin miner trojan. The names of the .exe file may be different, but the effects are almost always the same. Because coin miners aim at cryptocurrency mining, they utilize all possible hardware power of your personal computer to perform this operation. This virus does not take note of the fact that you probably need to use your PC for other tasks – it will consistently consume over 80% of your processor power.

Besides CPU utilization, some of the coin miners also utilize GPU power for their operations. In that instance, you will likely struggle also to see the mouse arrow moving – GPU is often used on 100%. It is not as vital as CPU for system work, so Qualityagent64.exe coin miner viruses don’t waste time on trifles and utilize it all. It sometimes may cause sad results.

Shortly about cryptocurrency mining

Cryptocurrency mining is a term that means the operation 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 powerful PC is needed. Exactly, the GPU is better for this task, because they have more cores available. Cryptocurrency mining farms are usually constructed of tens and hundreds of GPUs to conduct their activity effectively. Such computer systems are not usable for “general” 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

    “Visible” damage is not a solitary negative activity coin miners perform to your computer. Qualityagent64.exe coin miner likewise deals damage to your operating system. To carry out all malicious operations effectively, it wrecks the security features of your system. You will likely see your Microsoft Defender disabled – malware stops it to avoid detection. If you open the HOSTS file, you will likely see a load of new notes – they are added by this coin miner to connect your computer to a malicious mining network. All these changes shall be reverted to the initial state in the process of system recovery.

    Hardware effects of coin miner activity

    Besides slowing down your PC, running at peak level for a long period of time can trigger damage to your device and raise electricity bills. PC components are created to easily deal with high load, but they can do so only when they are in a good shape.

    Tiny and covered processor cooling system is hard to crack. Meanwhile, GPUs have large and easy-to-access fans, which can be easily broke if affected while working, for example, by the user much before the malware injection. Malfunctioning cooling system, together with the very high load caused by Qualityagent64.exe can easily lead to GPU failure3. Video cards are also prone to have fast wearing when used for cryptocurrency mining. It is surely a bad case when your GPU’s performance decreases on 20-30% just after several weeks of being exploited in such a way.

    How did I get Qualityagent64.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 malicious programs among “serious” malware. Adware sometimes serves as a carrier for Qualityagent64.exe malware infiltration: it shows you the banners, which have a link to malware downloading. Yes, this abstract “malware” can belong to any kind – another adware, spyware, rogue or backdoor. However, the statistics say that approximately 30% of all malware spread through the malicious banners are coin miners – and Qualityagent64.exe is just with them.4

    Unwanted banners adware

    The example of malicious banners you can see in the Internet

    An additional way you could get this item 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 demand the license key) have small chances to earn money. Therefore, there is a very big lure to include malware to the final package of the hacked app and acquire a coin for every installation. Before blaming these people for hacking and also malware distribution, ask yourself – is it okay to avoid purchasing the program in this manner? It is more affordable to pay $20-$30 at once than to pay a much bigger figure for antivirus software and new parts for your PC.

    How to remove the Qualityagent64.exe miner from my PC?

    The best way to get rid of this coin miner virus is to use anti-malware software

    Getting rid of such a virus involves the use of special software. Effective antivirus must have high performance at scanning and be lightweight – in order to make no problems with usage also on weak systems. On top of that, it is better to have proactive protection in your protection solution – to stop the virus even before it starts. Microsoft Defender lacks these elements for different factors. That’s why I’d recommend you to use a third-party anti-malware program for that objective. GridinSoft Anti-Malware is a perfect option that fits all of the mentioned qualities.5

    Before the virus removal, it is important to boot your system into Safe Mode with Networking. Since Qualityagent64.exe miner takes a lot of processor power, it is needed to stop it before launching the security program.

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