My questions are how do they do their action and how to prevent the malware installed in our PC. I think I have a bad issue with malware. one day when I install a walle from cheap unpolular coin, I detect malware after that I lost my eth balance. That was suck. After that I will never download and install any wallet from unknown and new developers. I prefer to use wallet in the exchanger instead installing on my PC.
Never try to download the suspicious thing, Those fucking hackers just try to beggar to the computer owners like putted the malware to the victim's computer or dekstop.
Just just spread that through the fake link or something else such as fool another person to use its software.
