If you are looking for heart-themed assets, programs, or design packs, use verified platforms:
: Even if not "malicious," these packs often install intrusive toolbars, change your search engine, or display constant pop-up ads. Safe Alternatives
: Use a trusted antivirus tool. You can also upload the file to VirusTotal to check it against dozens of security databases without opening it.
: If this is supposed to be a specific application, search for its official name on GitHub or SourceForge. What to do if you already downloaded it: Do NOT open it : Delete the file immediately.
