How did I get Avast-scan.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 acts as a carrier for Avast-scan.exe malware injection: it shows you the banners, which have a link to malware downloading. Sure, this abstract “malware” may belong to any kind – an additional adware, spyware, rogue or backdoor. But the statistics say that about 30% of all viruses spread through the malicious banners are coin miners – and Avast-scan.exe is right one of them.4
The example of malicious banners you can see in the Internet
One more way you could get this item on your computer is by downloading it from the dubious site as a part of a program. Users that spread hacked versions of favored programs (which do not require the license key) have small chances to make money. Therefore, there is a huge temptation to add in malware to the final package of the hacked app and acquire a coin for every setup. Prior to blaming these individuals for hacking and also malware spreading, ask yourself – is it alright to avoid purchasing the program in such a way? It is more affordable to pay $20-$30 one time than to pay a much bigger figure for antivirus software as well as new parts for your desktop.
