It’s been a long while since i used a desktop and honestly can’t remember what antivirus software i used, and even then, probably the landscape has changed over the years.
Atm i’ve been winging it with just Windows Defender (no custom configuration) and scanning any thing that looks suspicious on VirusTotal, but probably that would be not enough.
I’m thinking on get a couple of pirated files, so i’d like to be as secure as possible.
Use Common Sense™ brand antivirus. Pirated files like movies and songs are mostly ok except for executables. Those must be sourced from trusted sites. Pirating has its risks and if possible do it on another machine not used for work. Antivirus will almost always flag crackers and keygens anyways.
