No. Symantec/Broadcom removed all official K9 download pages in 2019.

Unlikely. Driver conflicts and browser compatibility will probably cause installation failure or system instability.

Treat it as suspicious. Scan it with VirusTotal, check the digital signature, and run it only in a sandbox. Most such sites distribute malware.
Q4: Does K9 still block websites after discontinuation?
Yes and no. The local filter may still work based on its last blocklist (circa 2018), but new domains won’t be categorized, and HTTPS sites will produce certificate errors.

Likely yes. Most modern antivirus suites (Windows Defender, Malwarebytes, etc.) detect K9 as a PUP or unsecured application due to its age and network interception method.
