First off, if you want to be sure if its a false positive for anything, there is a site out there that allows you to have them scan the program and tell you if it is a false positive or not, you can read the article here:

Here is the latest scan of VLC:

When it comes to anti virus programs, everyone has their own opinions. I am a gamer, so Norton and McAfee are garbage to me because they are resource hogs, and they are large in size. When gaming, I want something lightweight and does the job. Another thing is when I said it's one of the worse, I am taking all aspects of the program into count and not just what its primary job is.
Now onto free video editing programs, or cheap video editing programs that can handle OBS, well, I am pretty sure if you are using Windows Movie Maker, it can handle recordings of OBS. Just try different recorded file types. I know with OBS, I am recording to file type .mp4, and I think by default, its .flv. You can change that in the settings of OBS or remux the video iwith OBS if that is the case. Other than that, you can check out here:

I know you said,
But any other free or cheap program your going to use will be a 3rd party software which you more and likely wont know. Best thing is, before downloading it, do a little research on it. It only takes a few seconds to go to Google, Ask.com, or Bing to do a search on the program your about to download and read reviews or comments from others that use it.
As for the original poster using VLC to edit his recordings, I just looked into it more and found that their video editing software is still in development and VLMC, (VideoLAN Movie Creator), can't be downloaded, so I am not really sure what he was trying to use VLC for since that is just a player and not a editor. More on that can be read here:

Note:
Though I agree with Sapiens, his wording could have been better. But you ask, "So now my posts are false.", I would say yes for that one post because you are flat out saying
You are stating there that VLC is unsafe, which it is not. Many companies have reviewed it along with many people.
As for Norton being a top rated, that is not false, depending on who did the ratings. I seen some where it's in the top 5, and I seen some where its not even a contender in the top 10, eg:

But that again will all be opinion based.
Overall, I wish I could tell you a better software for video editing, but I can only tell you what I have used and that is just Windows Movie Maker years ago and Sony Vegas. but like I said, the problem could be just the file type you are recording to within the OBS settings.
