I am looking for a save free video joiner that doesn't install spyware/malware and a place to download it?
There is an application called AviDemux which is currently open source and available for downloading. The software allows the user to trim and join videos. It's hosted on SourceForge, which means it's completely out of malware or spyware installations.
