Ubuntu 20.10 Slow app Loading

Thank you for the link @Mina. I must still be a bit wet behind the ears, just off the boat, newcomer, or things just don’t connect like they use to.
Now I find out there is not only DEB and Snaps, but also AppImage, RPM. Flatpak, and source code to deal with.
I’m still kind of new to Linux (about 2 years now) and I suppose I was looking for a way to “trust” a software package that I might be thinking of installing. In Windows, I use to always run a virus scan on the download before installing.
Maybe it not as simple in Linux. But I get the feeling that packages install via deb can be trusted. Maybe I’m wrong. It looks like LM does not trust snaps?
Like you said in another posting elsewhere that it’s a personal choice & responsibly to review / look into the software a person installs on their system. I suppose I was looking for an easy way out.
