I'm new to this exploit scheme, I wanted to take some questions.

Some exploits are obfuscated

this obfuscation nature are detected by win10 defender but Im pretty sure not for other anti virus. I use kaspersky none of them are detected because they are just 'obfuscation nature'

for dll some are detected because of the game manipulation and obfuscation natures

Reason why these are being flagged is because of multiple reasons,

obfuscation: this is code that stop users from gathering code from inside of krnl or just any readable source.

Nature: all exploits with an api will always be flagged due to the api, this because of its nature and the way it multiplates roblox to do all the stuff that an exploit should do like execution.

Powerful api: the api for krnl is powerful and will be flagged as higher as normal than any other api like wearedevs api, this is due to obfuscation as I said above and the functions that go inside of roblox for the krnl api to attach and execute powerful scripts 

But at the end of the day,  most exploits will be flagged as a false positive, but still be careful when you download in the future some might not even attach  to roblox but attack to your personal data.

I reccomend to.anyone if your gonna download an exploit either get a $15+ exploit none of the below or head to WeAreDevs or any trusted exploit page to download reputable and safe exploits.

If u have a problem downloading or the krnl app disappearing u can go into windows defender and disable real time protection, then what u wanna do is create a exclusion when creating an exclusion a file prompt should show up then u want to find the folder where the exploit is located, if it is located in your desktop then head over to your desktop and click it then that folder and everything inside should not be affected by any anti virus.
