What is Tahoo.exe process?
Tahoo.exe is a malicious process created by coin miner virus
As I have specified earlier, Tahoo.exe is a coin miner trojan virus. The names of the .exe file may be different, but the impacts are usually the same. Because coin miners aim at cryptocurrency mining, they use all possible hardware capacity of your personal computer to perform this process. This virus does not pay attention to the fact that you probably need to make use of your computer for other tasks – it will consistently use over 80% of your processor power.
Tahoo.exe – Very high CPU and GPU usage
Besides CPU consumption, some of the coin miners additionally utilize GPU power for their tasks. In that instance, you will struggle also to see the mouse cursor moving – GPU is usually utilized on 100%. It is not as vital as CPU for system work, so Tahoo.exe coin miner viruses don’t waste time on trifles and utilize it all. It sometimes can result in unhappy effects.
Shortly about cryptocurrency mining
Crypto mining term means the operation of calculating the transaction block hash. That is a basic part of anything based on the blockchain technology. Since this operation takes a lot of calculations, a high-end PC is required. Exactly, the video card 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 computer systems are not usable for “usual” purposes, like gaming or web browsing. Fraudsters who make profit via this coin miner use someones’ PCs instead, even if they are used for the regular activity.2

“Visible” damage is not a solitary negative activity coin miners do to your system. Tahoo.exe coin miner additionally deals damage to your operating system. To conduct all malicious operations effectively, it wrecks the security features of your system. You will likely see your Microsoft Defender disabled – malware stops it to prevent detection. If you check the HOSTS file, you will likely see a number of new notes – they are brought in by this coin miner to connect your PC to a malicious mining network. All these changes are about to be thrown back to the original in the process of computer recovery.
Hardware effects of coin miner activity
Besides slowing down your PC, running at peak power for a long period of time may trigger damage to your machine and raise power bills. PC elements are designed to easily deal with high load, but they can do so only in case when they are in a good shape.
Little and well-protected CPU fan is quite hard to broke. Meanwhile, GPUs have big and easy-to-access rotors, which can be easily broke if affected while spinning, for example, by the user much earlier before the malware injection. Malfunctioning cooling system, together with the unusually high load caused by Tahoo.exe malware can easily lead to graphic processing unit failure3. Graphic cards are also prone to have increased wearing when used for cryptocurrency mining. It is likely an unwanted situation when your GPU’s performance decreases on 20-30% only after several weeks of being exploited in such a way.
How did I get Tahoo.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 malevolent programs through “serious” malware. Adware frequently serves as a carrier for Tahoo.exe malware infiltration: it shows you the banners, which have a link to malware downloading. Sure, this abstract “malware” can belong to any type – yet another adware, spyware, rogue or backdoor. But the statistics say that approximately 30% of all viruses spread with the malicious banners are coin miners – and Tahoo.exe is just one of them.4
The example of malicious banners you can see in the Internet
One more way you could get this thing on your computer is by downloading it from the untrustworthy 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 get paid. Therefore, there is a huge temptation to include malware to the final package of the hacked app and get a coin for each installation. Prior to blaming these guys for hacking and malware spreading, ask yourself – is it alright to avoid paying for the program in such a way? It is much cheaper to pay $20-$30 at once than to pay a much greater sum for antivirus software as well as new parts for your computer.
How to remove the Tahoo.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 using special tool. Proper security tool must have high efficiency at scanning and be lightweight – in order to make no problems with utilization even on weak systems. In addition, it is recommended to have on-run security in your protection tool – to stop the virus even before it starts. Microsoft Defender does not have these elements for various reasons. That’s why I’d suggest you to use a third-party anti-malware program for that purpose. GridinSoft Anti-Malware is an ideal choice that fits all of the specified characteristics.5
Prior to the virus removal, it is important to reboot your Windows into Safe Mode with Networking. Since Tahoo.exe miner consumes a lot of CPU capacity, 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.

When your computer is in Safe Mode, all third-party programs, just like the majority of non-crucial operating system components, are not started with the system start. That gives you the ability to clean the PC without dealing with high processor usage of the coin miner.
