Is MBAM better, or is microsoft defender enough if you download from trusted sources?
Do you consider Nyaa safe? (I’d like to get a visual novel or two that I haven’t purchased on steam yet)
Regarding other games, I always used pirate bay and I’ve been fine, 10 years ago though. Are the website listed in the wiki generally safe?
Yes and No. You should be able to set some GroupPolicies, and execute games by that type of policies like Application Guard. (Search GPO).
