7-zip.dll is a core component of 7-Zip, the well-known and OPEN SOURCE file archiver application for Windows. Its open source, idiots, and has NO reported malware, therefore should be regarded as not "essential" but quite useful and completely safe. By comparison, Windows itself is a deathtrap. God almighty you folks are total tards. I use 7-Zip on 8 Windows machines and wouldn't imagine not having it installed (due to windows brain damaged zip capability).
  Stuffit, tard. This site is lame.   (further information)

I downloaded 7-zip. So many others rated it hightly, It also download about six other programs at the same time. Diffifcult to remove those unnessary those six. I do not trust 7-zip.dll just because you can not remove the thing even after deleting the 7-zip program. Go figure? Harmless? I say not harmless.

It is simply a dynamic-link library file that installs along with the 7-zip executable program. I have installed; uninstalled; re-installed, and used this program over the past two years. I find it very easy to use (and uninstall if needed), and safe.

7-zip should be the standard for all un/compression work on windows systems. to people like "robert h.": if you downloaded some stuff, and it installs something strange, it was not the original software. in moments like these, i ask myself, where do people like you download software? in the "dark-web", or on "xxx-portals"? never heard about, that you have to take care of yourself and the hard and software you use? would you jump from a house and if you would not die, then you would sue the architect of the building? man oh man...!!! people like you should not be allowed to have internet-capable-devices at all. that's it.

Always remember to perform periodic backups, or at least to set restore points.

Should you experience an actual problem, try to recall the last thing you did, or the last thing you installed before the problem appeared for the first time. Use the 6resmon command to identify the processes that are causing your problem.
