What is V4_tool.exe process?
V4_tool.exe is a malicious process created by coin miner virus
As I have pointed out before, V4_tool.exe is a coin miner trojan virus. The names of the executive file may be different, however, the impacts are generally the same. Because coin miners aim at cryptocurrency mining, they use all available hardware power of your desktop to conduct this process. This malware does not take note of the fact that you may want to make use of your machine for other tasks – it will consistently take over 80% of your processor power.
Besides CPU consumption, some of the coin miners additionally utilize GPU power for their tasks. In that instance, you will probably struggle even to see the mouse arrow moving – GPU is usually utilized on 100%. It is not as essential as processor for system work, so V4_tool.exe coin miner viruses do not waste time on trifles and utilize all of it. It sometimes may cause bad results.
Shortly about cryptocurrency mining
Crypto mining term means the action 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 machine is required. Exactly, the GPU is better for this task, because they have more cores available. Cryptocurrency mining farms usually consist of tens and hundreds of graphic cards to complete their task efficiently. Such systems are not usable for “general” purposes, like gaming or browsing the Web. Fraudsters who make profit via this coin miner use someones’ computers instead, even if they are used for the regular activity.2

“Visible” damage is not a solitary bad activity coin miners do to your computer. V4_tool.exe coin miner likewise deals damage to your operating system. To complete all malevolent functions properly, it wrecks the protection components of your system. You will likely see your Microsoft Defender disabled – malware halts it to avoid detection. If you check the HOSTS file, you will likely see a load of new entries – they are added by this trojan miner to connect your PC to a malicious cryptomining network. All these adjustments are about to be gone back 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 long times may trigger damage to your machine and increase electricity bills. Hardware elements are designed to easily get along with high load, but they are good with it only in case when they are in a good shape.
Tiny and well-protected processor cooling system is hard to broke. Meanwhile, GPUs have big and easy-to-access fans, which can be easily broke if affected while spinning, for instance, by the user much before the coin-miner injection. Malfunctioning cooling system, together with the very high load caused by V4_tool.exe can easily lead to GPU failure3. Video cards are also tend to have increased wearing when used for crypto mining. It is surely an undesirable case when your GPU’s performance plunges 20-30% only after several weeks of being exploited in such a way.
How did I get V4_tool.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 sometimes acts as a carrier for V4_tool.exe malware injection: it shows you the banners, which contain a link to malware downloading. Sure, this abstract “malware” can belong to any kind – yet another adware, spyware, rogue or backdoor. But the statistics say that around 30% of all malware spread with the malicious banners are coin miners – and V4_tool.exe is just with them.4
One more 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 who spread hacked versions of well-known programs (which do not demand the license key) have small chances to get paid. Therefore, there is a very big temptation to include malware to the final package of the hacked application and receive a coin for each installation. Prior to blaming these people for hacking and malware spreading, ask yourself – is it OK to avoid purchasing the program in this manner? It is more affordable to pay $20-$30 at once than to pay a much bigger sum for antivirus program and new parts for your desktop.
