I'm using torrents not just to download movies but software as well and this is helpful for me since I'm not aware that there's that kind of virus the only virus I know that is connected to cryptocurrency is the ransomware wherein you're going to pay crypto in order to unlock your files, thanks for this valuable information.
May I ask for some suggestions for everyone? What are the things we should do in order to avoid this? or what kind of antivirus do you think is helpful to avoid this.
You can't avoid it 100%
Possible solution:
Create 2 folders (disks, PCs, etc...) one for the sensitive and important data (family photos, etc...), and the other for the rest (films, music, downloadable stuff). Backup the sensitive data folder regurarly onto an external HDD (once a week, month, depends on) and when a ransomware hijack your PC, you'll just erase the complete system, install a brand new and you can copy your sensitive data back from the backup, problem solved. You should not forget to use a proper antivirus of course, but antivirus is a prevention and this is a solution.
If you are paranoid enough, you can keep the backup HDD offsite, in a safebox, create copies and store it in differen places etc... you can decide how valuable the information you want to protect and what is the maximum effort you want to take to protect it.
