People (rightly) shit on Windows but Defender, despite constantly flagging my windows activator as malware, is the best antivirus that’s ever happened. If that fails (occasionally I have a family member who needs help) the amazing Malwarebytes takes care of it with one scan.
If that fails, whatever—reformat. Reformat never fails hahaha.
I haven’t got a virus once in my life, and I’m old. But like you, I stick to trusted sources. Even back on Kazaa, I made sure I’m not running an exe or bat and I was totally fine. The worst thing that happened to me was fucking with the mean clock in AOHELL TOOLZ too much and it put like a thousand text files title FUCK YOU in windows folder, circa windows XP. Luckily deleted them before my dad found out. Took FOREVER with a 400MHz Celeron.
At least it didn’t infect me with CIH, like it threatened (it told me the previous clock did that if you clicked it too much.)
