Do I really need Antivirus?

Do I really need this meme?
I have windows "defender" & Malwarebytes.
Windows 10, have the last updates
and I have a brain.
not downloading any shit or crap.
I never open single link from spam email or any bullshit
I don't believe any facebook "2017" scam or phishing.
most of my games I download from steam or IPT.
using qBittorrent & LibreOffice and a lot of open source software.
every scan I do with Malwarebytes I found out my PC is clean and nothing to worry about
maybe sometimes there's alert because of "trainer" (cheat for a game).
one day I download HitmanPro and he only found out that I have tracking cookies and nothing (he found out I have KMSpico but all good)

I had using also a laptop and I had their NOD32 internet security and he was fine for few month and then he became shit, killing memory and more.

I had a friend who using Bitdefender antivirus free and it works fine and great for him, I read many reviews about this antivirus and found a lot of great feedback from him.

but let's go back to really question here.
do I really need Antivirus?
since 2015 till now, I still don't have any antivirus.
(only windows "defender" & Malwarebytes)

Doesn't hurt to have. Can cause problems when accessing Your own files.

If you go to porno websites or shady sites, even by accident, I'd get an antivirus, user. Better safe than sorry

Yes but you need a paid one like Kaspersky because it's much better and keeps you safer against stealth malware

Enjoy banning kaspersky if u live in uk or us.

There's lots of poorly protected hardware and dumb users that they alone are enough to prey on, without wasting effort on someone like you OP, who knows what not to do.

I'm inserting my naughty little viruses into your tight little OS holes right now hoh hoh hoh ;) ;)

Always better having one. Don't listen to people saying common sense 2017 is enough.
I've been using Nod32 for years and it works good.

I didn't like NOD32. I had few problems with him on my laptop

Avast Free is just shit-tier now. What's about Avira?
