That was actually going to be my first choice. From what I read it seems better polished than others. But then I read some recent lab tests in which ESET missed blocking a ransomware attack. And that's the threat model that worries me the most.

Any anti-virus can miss a malware at any time because they rely on updates which take at least a day if not more to be prepared and tested before being distributed in the updates. Don't worry about ESET missing one ransomware attack in a lab test. Do backups daily.

I run ESET for the only reason that it was offered to me cheaply and has worked fine over the years without feeling intrusive.
