Oh I run Windows 11 too on two systems (another runs Vista, and one runs XP) but I prefer the UI of Vista and XP over anything 'modern' but I credit Windows 11 for at least attempting to reboot skeuomorphic UI. Still about as half done as Windows 10 though. Stops at icons.
I longingly await the death of flat UI design.
I'd steer clear of MalwareBytes though. That Crapp has caused the PC at work to run like an i486. It chews through RAM, makes it freeze every 8 hours, and has somehow redirected Google searches to some foreign clone (results are quite hilarious though).
I'm convinced it's either malware or owned by Cheetah Mobile with how it affected the system. If it's not doing the above it's slowing the system down popping up endless things about updates. I hate it. I turned it off three times but stupid boss keeps re-enabling it. I never heard of it until I saw it in action, but I'd rather stick with tried and true Norton or McAfee.
