I usually do not reply to this troll comments, but gosh you made me scream out loud here. The fact that you believe that using no security in 2019 makes you -somehow- superior than other users, just reflects how little you know about the attack vectors nowadays. Anyways, I will not cry about it. Thanks to these kind of comments is that many of us have a job
To be fair, if someone updates, uses a webviewer for attachments, uses one of the big browsers with Safe browsing & flash blocked, uses mostly apps from windows store, blocks all incoming connections, the chance of infection is indeed tiny. My AV is really collecting dust.
My partner knows nothing about security, she’s just careful, uses web viewers and updates, I’ve installed Sophos on her machine and we have a UTM Firewall at home, they’ve never flagged anything real.
Being careful and safe practices are not to be underestimated.
In Ubuntu the chance of a infection is even smaller as when someone only uses snap apps, they auto update during usage, are sandboxed and also come with an apparmor profile at installation time
