u2k Virus has effected my Friends laptop

They ransomed the entire health service here in Ireland during the pandemic. https://en.wikipedia.org/wiki/Health_Service_Executive_ransomware_attack

Total scumbags. Some patients had to have procedures postponed. It was insane. They have no conscience at all.

That's a good point. Viruses of old used to make themselves known pretty fast. Most recent ones are sneakier and can operate hidden for a while before you even know they're there... which also makes backups problematic when ransomware is involved.

I don't know, maybe it's all about general scrupulousness with my PC and understanding when you should open random file and when you're not. I dust my PC regularly, changing thermal interfaces every year or so and always controlling things like temps, voltages and CPU, GPU, SSD, RAM or whatever load. It's not OCD, just my buzz bug, to always check performance and all the things connected, I just love doing it since my childhood. So I never really had anything stolen e.g. passwords or credit cards info and didn't see any banners with demand of money to encrypt your data.

P.S. To better understand what weirdo I am - usually, when I first launch some demanding game I start it with MSI afterburner on, checking the CPU/GPU load, correcting frametimes by limiting FPS in driver to e.g. 55, my way is just crank everything to ultra and make it work as smoothly as possible on my config. And I always encounter bugs in games, even in most polished ones. Where my friends are having hitch free experience, I manage to crash the game etc. So maybe my option is to become QA someday :D Sometimes it is just the hardware combination which causes games to break, but a few times I helped my friends to find bugs and stutters on their own machines.
