How did I get Culdwnf.exe coin miner virus?

Coin miners are the most prevalent malevolent programs among “major” viruses. Adware often works as a carrier for Culdwnf.exe malware injection: it demonstrates you the banners, which contain a link to malware downloading. Yes, this abstract “malware” may belong to any type – an additional adware, spyware, rogue or backdoor. But the statistics say that about 30% of all viruses spread through the malevolent banners are coin miners – and Culdwnf.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 popular programs (which do not require the license key) have small chances to earn money. Thus, there is a very big temptation to add in malware to the final package of the hacked application and get a coin for every setup. Prior to blaming these individuals for hacking and also malware spreading, ask yourself – is it okay 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 bigger sum for antivirus program and new parts for your desktop.
