It really seems unnecessary to spend money on security products, things have evolved and there are almost no longer or it is very rare to see rootkits, Trojans, etc... This goes against the industry, I know... Now there is Ransomware, scams and phishing. As opposed to ransomware, although there are free products, the best thing is the backup, as opposed to the social engineer, which is the most common thing used by cyber criminals, there are different methods of defense, so to say, and it doesn't necessarily have to do with security products such as antivirus or anti-whatever. In short, it's just an opinion. I say this of a charlatan that I am because I am not an expert in computer security. Best regards.
