Chrome (and some antiviruses) dislike Feralheart because it's an uncommon download. There is no malicious software inside the setup/download.
Simply just use another browser besides Google Chrome and lower your antiviruses temporarily. ^^
If you want to turn off phishing and malware detection for Chrome, then follow these steps.
(1) Click the Chrome menu (https://storage.googleapis.com/support-kms-prod/SNP_9721C573E41777FBA43E1498AD084E3B160C_2696434_en_v2) on the browser toolbar.
(2) Select Settings.
(3) Click Show advanced settings and find the "Privacy" section.
(4) Deselect the "Enable phishing and malware protection" checkbox. Note: When you turn off these warnings you also turn off other malware and phishing alerts.
