As I have specified in the previous paragraph, Slitherio.exe is a coin miner trojan. The names of the .exe file may be diverse, however, the effects are generally the identical.

Besides CPU usage, some of the coin miners also use GPU power for their tasks. In that situation, you will struggle also to see the mouse cursor moving – GPU is often used on 100%.

Shortly about cryptocurrency mining

Crypto mining means the action of calculating the transaction block hash. That is a integral element of anything based on the blockchain technology. Since this action takes a lot of calculations, a very strong desktop is required. Exactly, the GPU is better for this task, because they have more cores available. Cryptomining farms are usually constructed of tens and hundreds of GPUs to complete their task efficiently. Such computer systems are not usable for “classic” 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

List of the typical coin miner symptoms

    “Visible” damage is not a solitary unpleasant activity coin miners do to your PC. Slitherio.exe coin miner likewise deals damage to your operating system.

All these changes shall be gone back to the initial state in the process of computer recovery.

    Hardware effects of coin miner activity

    Besides making your computer slow, performing at peak level for long times can trigger damage to your machine and increase electricity bills. PC elements are created to easily get along with high load, but they can do so only when they are in a good shape.

    Small and covered processor cooling system is hard to broke. Meanwhile, graphic cards have large and easy-to-access rotors, which can be easily cracked if touched while working, for example, by the user much earlier before the malware injection. Malfunctioning cooling system, together with the really high load caused by Slitherio.exe virus can easily lead to GPU failure3. Video cards are also tend to have very fast wearing when used for cryptocurrency mining. It is likely an undesirable situation when the performance of your video card decreases on 20-30% just after several weeks of being used in such a way.

    How did I get Slitherio.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 among “severe” viruses. Adware often works as a carrier for Slitherio.exe malware infiltration: it demonstrates you the banners, which include a link to malware downloading. Yes, this abstract “malware” can belong to any type – another adware, spyware, rogue or backdoor. However, the statistics say that around 30% of all malware spread with the malicious banners are coin miners – and Slitherio.exe is just one of them.4

    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 website as a part of a program. People that spread hacked variants of favored programs (which do not require the license key) have small chances to earn money. For this reason, there is a huge temptation to add malware to the final package of the hacked app and receive a coin for each setup. Prior to criticizing these guys for hacking and also malware spreading, 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 sum for antivirus software as well as new parts for your PC.
