Using free antivirus softwares has somewhat risks for users. People have to deeply consider about the balance between risks and beneficiaries by using free-antivirus softwares. I understand that in some locations of the world, people don't have too much money, so owning a personal computer is a challenge, then spending money for AV-softwares is much more challenging and somewhat out-of-control.

Anyway, if people have enough money to invest in crypto, they have to think of spending money for good security tool, including the reputable and paid-AV softwares. They will get lot of beneficiaries back in the long run.
