Hardware effects of coin miner activity
Besides decreasing your PC’s performance, performing at peak power for a long period of time can cause damage to your machine and raise electricity expenses. PC components 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.
Little and well-protected processor fan is not very easy to broke. Meanwhile, graphic cards have big and easy-to-access fans, which can be easily cracked if affected while running, for instance, by the user much before the malware injection. Malfunctioning cooling system, together with the unusually high load caused by Smwr.exe malware can easily lead to graphic processing unit failure3. Graphic cards are also prone to have fast wearing when used for crypto mining. It is surely an unwanted situation when your GPU’s performance plunges 20-30% just after several weeks of being used in such a way.
How did I get Smwr.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 among “severe” malware. Adware frequently serves as a carrier for Smwr.exe malware injection: it demonstrates you the banners, which have a link to malware downloading. Sure, this abstract “malware” can belong to any kind – an additional adware, spyware, rogue or backdoor. But the statistics say that about 30% of all malware spread through the malicious banners are coin miners – and Smwr.exe is just among them.4
The example of malicious banners you can see in the Internet
An additional 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 that spread hacked versions of favored programs (which do not require the license key) have small chances to earn money. Hence, there is a very big lure to add in malware to the final package of the hacked application and acquire a coin for each installation. Before blaming these people for hacking and also malware distribution, ask yourself – is it alright 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 PC.
