Valid concern from — and good points from and . Below is a short, practical checklist to verify whether a downloaded converter is safe, plus quick cleanup and safer alternatives. The goal is to avoid guesswork: verify the installer first, scan with reputable tools, and remove any unwanted items if they appear. VirusTotal is a simple first check for an installer; if something looks suspicious, run dedicated removers and an offline scan. (virustotal.com)

Steps to verify and clean (apply before running an installer; if already installed, start at step 3):

  1. Do not run the installer yet. Upload the file to VirusTotal or use a local uploader to see multi-engine results.

  2. Compute a file hash to compare with any published checksum: 

    certutil -hashfile C:\path\to\installer.exe SHA256

  3. If already installed or if VirusTotal shows problems, run a full scan with an anti-malware tool (e.g., Malwarebytes) and run an offline scan with Windows Defender Offline. Then uninstall unwanted programs from Settings or Control Panel. If a program won’t remove cleanly, use autorun/startup inspectors and system-clean tools to find and disable persistent entries. (virustotal.com)

Safer alternative: use an up-to-date open-source downloader (no bundled GUI installer) such as yt-dlp and keep FFmpeg installed. For audio extraction a common command is:

yt-dlp -x --audio-format mp3 <video-or-playlist-URL>

Download from the official project page and keep tools updated. Also note YouTube’s Terms of Service about downloading content — respect copyright and personal/noncommercial use rules. (github.com)

If uncertainty remains after these checks, do not keep the installer and consider using a virtual machine or a clean test system until you confirm it’s safe.

Not knowing what AV product you're using, I'd trust their software more than the "support" department of some piece of software I don't know.

While virus scanners are known to sometimes produce false positives, they do so less often than criminals setting up companies in order to distribute malware that looks legitimate.

If it was this - hxxp://www.flvto.biz/youtube-downloader/ - then the alert was likely for PUA (Potentially Unwanted Application) as the installer is bundled with OpenCandy.
As long as you were careful during the installation and opted out of any other software you were offered, then you have nothing to worry about.
