HTTPS protects the connection to the named server when certificate validation succeeds. An HTTP download lacks that transport protection. Neither scheme alone establishes that the application is legitimate, so source identity and file provenance still matter.
Use a documented secure route
Prefer a secure download endpoint published by the relevant source. Do not silently change an old HTTP link to HTTPS and assume the same file exists there. The server must actually support the secure endpoint.
Respect warnings
A certificate or unsafe-download warning should not be dismissed automatically. Check the address and source, and ask for a supported current link if needed. Avoid turning off verification globally to obtain one installer.
Separate transport from software trust
A securely downloaded malicious file is still malicious. Conversely, a familiar filename is not proof of integrity. Publisher verification, platform protections and a trustworthy update channel remain useful parts of evaluating an installer.
