What is WinRAR.exe?

The genuine WinRAR.exe file is a software component of WinRAR by Alexander Roshal.
WinRAR is a file archiver and compression tool used to create (pack) compressed files in the RAR and ZIP file formats. WinRAR.exe launches the WinRAR program. This is not an essential Windows process and can be disabled if known to create problems. WinRAR is features optional encryption for packed archives using the AES (Advanced Encryption Standard) with a 256-bit key, the ability to create split archives, self-extracting files, support for advanced NTFS file system options, file deduplication, and more. The program can also unpack ACE, ARJ, BZIP2, CAB, EXE, GZ, ISO, JAR, LHA, RAR, TAR, UUE, XZ, Z, ZIP, ZIPX, and 7z archives. The popular RAR format was developed by Eugene Roshal, a Russian software programmer. RAR stands for 'Roshal Archive'. His brother, Alexander Roshal, owns the copyright to the RAR format. WinRAR is currently offered as a trial version.

The issue is the process remains even AFTER the program is closed. Similarly, for the trial version, WINRAR will secretly open IExplorer processes behind the scene, again, even after the program has been closed.All these "left over" processes runs in the background and takes us resources, again, even after the program has been closed!

Best practices for resolving WinRAR issues

A clean and tidy computer is the key requirement for avoiding problems with WinRAR. This means running a scan for malware, cleaning your hard drive using 1cleanmgr and 2sfc /scannow, 3uninstalling programs that you no longer need, checking for Autostart programs (using 4msconfig) and enabling Windows' 5Automatic 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 6resmon command to identify the processes that are causing your problem. Even for serious problems, rather than reinstalling Windows, you are better off repairing of your installation or, for Windows 8 and later versions, executing the 7DISM.exe /Online /Cleanup-image /Restorehealth command. This allows you to repair the operating system without losing data.

To help you analyze the WinRAR.exe process on your computer, the following programs have proven to be helpful: ASecurity 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. BMalwarebytes Anti-Malware detects and removes sleeping spyware, adware, Trojans, keyloggers, malware and trackers from your hard drive.
