TCLights v2.4 (Siren/Strobe Program)

[[TC]»Elmo«]

I guess the heuristics scan has found some similarities with said Trojan and assumed it's nasty.

TCLights2 has very simple code and some of it would proably look similar to a keylogger or similar (it uses a low-level windows API to scan for pgup/pgdn key-presses).

If it's still causing a problem, I can try submitting it to Microsoft as a false positive - I can't test it on mine, because Windows Defender refuses to run while my third party anti-virus is active.

For curiosity, I uploaded it to VirusTotal to check and it got detected by 0/54 scanners:
