If you downloaded it from the official website ,absolutely nothing to worry about.
An absolutely ignorant and bullshit statement. There are so many attacks that can be executed by space-sponsored attackers while you "download from the official website". If you don't:
1) Verify the hashes, OR
2) Compile from source yourself,
Then there is absolutely no way you can claim that there is "absolutely nothing to worry about". Stop posting about matters in which you clearly lack knowledge.
Ah windows defender smartscreen in windows 10.
Whilst I'm unsure what your exact issue is, disable this bloatware from MS. All it does is spy on you and doesn't really help.
