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.
The only case where I’d use a virus scanner is when I’d host a file server for Windows systems.
Btw, ClamAV is slow and generally awful. It has many false positives that you get spammed all the time. There are also cases where it doesn’t really find the virus (false negatives). It’s also buggy and it’s not a good sign for security product.
I’d still recommend Linux, if you want to be safe. Windows has never been designed with security in mind. It’s not even a proper multiuser system.
ClamAV is fine as an AV. (Albeit, Designed for mail.)
As long as you aren’t downloading anyting stupid, you should be fine.
Plus, Common Sense is the best AV.
