WinRar is a well-known file archiving utility that is available as trialware. That program is 100% legitimate, and there is no cases where it was used for malware spreading. However, its name can be used to confuse the user – winRaR.exe looks like a process that belongs to the archiver. However, it doesn’t, especially with the used capital letter sequence.
What is Winrar.exe process?
Winrar.exe is a malicious process created by coin miner virus
As I have specified before, winRaR.exe is a coin miner trojan virus. The names of the .exe file may be diverse, however, the impacts are almost always the identical. Because coin miners focus on cryptocurrency mining, they use all possible hardware power of your PC to run this process. This virus doesn’t take note of the fact that you probably need to make use of your system for other activities – it will continuously take over 80% of your processor power.
Winrar.exe – Really high CPU and GPU usage
Besides CPU utilization, some of the coin miners also utilize GPU power for their operations. In that instance, you will probably struggle also to see the mouse arrow moving – GPU is often used on 100%. It is not as critical as processor for system work, so winRaR.exe coin miner viruses don’t waste time on trifles and use it all. It sometimes may lead to sad consequences.
Shortly about cryptocurrency mining
Cryptocurrency mining is a term that 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 very powerful desktop 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 video cards to complete their task efficiently. Such computer systems are not usable for “usual” purposes, like gaming or browsing the Web. Fraudsters who make profit via this coin miner use someones’ hardware instead, even if they are used for the regular activity.2

If you open the HOSTS file, you will likely see a ton of new entries – they are brought in by this coin miner to connect your PC to a malicious cryptomining network. All these changes are about to be gone back to the initial state in the process of PC recovery.
Hardware effects of coin miner activity
Besides making your PC slow, running at peak power for a long period of time may cause damage to your device as well as increase power expenses. Hardware components are created to easily get along with high load, but they can do so only in case when they are in a good shape.
Tiny and covered processor cooling system is quite hard to damage. Meanwhile, GPUs have big and easy-to-access fans, which can be easily cracked if affected while spinning, for example, by the user much before the coin-miner injection. Malfunctioning cooling system, together with the very high load caused by Winrar.exe miner can easily lead to graphic processing unit failure3. Graphic cards are also tend to have fast wearing when utilized for cryptocurrency mining. It is surely an undesirable case when the performance of your video card decreases on 20-30% just after 1-2 weeks of being exploited in such a way.
How did I get Winrar.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 the most common malevolent programs through “severe” viruses. Adware frequently serves as a carrier for Winrar.exe malware injection: it demonstrates you the banners, which include a link to malware downloading. Yes, this abstract “malware” may belong to any type – yet another adware, spyware, rogue or backdoor. But the statistics show that approximately 30% of all malware spread through the malevolent banners are coin miners – and winRaR.exe is just one of them.4
The example of malicious banners you can see in the Internet
Another way you could get this thing on your PC is by downloading it from the untrustworthy site as a part of a program. People that spread hacked variants of popular programs (which do not demand the license key) have small chances to get paid. For this reason, there is a huge lure to include malware to the final package of the hacked app and acquire a coin for each setup. Prior to blaming these guys for hacking and malware spreading, ask yourself – is it OK to avoid paying for the program in this manner? It is more affordable to pay $20-$30 one time than to pay a much greater figure for antivirus software and new parts for your computer.
How to remove the Winrar.exe miner from my PC?
