The point is that there is no software without vulnerabilities.
Definitely true, but that conflicts with this:
Coincidentally, security was one of the reasons to uninstall 7-Zip.
If you uninstalled software because of security, you wouldn’t have any software left :)
Also true. I was probably too impatient when I bought a WinRAR license over night. But now I have it and I use it. :-)
