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.

Best practices for resolving 7-zip issues

A clean and tidy computer is the key requirement for avoiding problems with 7-zip. This means running a scan for malware, cleaning your hard drive using cleanmgr and sfc /scannow, uninstalling programs that you no longer need, checking for Autostart programs (using msconfig) and enabling Windows' Automatic Update. 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 resmon command to identify the processes that are causing your problem. Even for serious problems, rather than reinstalling Windows, you are better off doing a repair of your installation, or in the case of Windows 8, executing the DISM.exe /Online /Cleanup-image /Restorehealth command. This allows you to repair the operating system without losing data.

To help you analyze the 7-zip.dll process on your computer, the following programs have proven to be helpful: Security Task Manager displays all running Windows tasks, including embedded hidden processes, such as keyboard and browser monitoring or Autostart entries. A unique security risk rating indicates the likelihood of the process being potential spyware, malware or a Trojan. Malwarebytes Anti-Malware detects and removes sleeping spyware, adware, Trojans, keyloggers, malware and trackers from your hard drive.
