What is runner.exe?

The genuine runner.exe file is a software component of Idle Crawler.
Idle Crawler is a known (PUP) potentially unwanted program that is often bundled and installed with other programs downloaded from untrustworthy sources. Runner.exe runs the Idle Crawler application. Idle Crawler often utilizes critical system resources and slows down computers. The program creates two processes, Chrome.exe or Navigate.exe, that send out web requests to unknown servers. The program also creates two tasks in the Window Task Scheduler, Special IC Runner and Advanced IC Updating, that will launch Idle Crawler on system startup. Special IC Runner checks whether Idle Crawler is running, whereas Advanced IC Updating proceeds to download new instructions for Idle Crawler. The presence of this program on the system makes it very likely that other PUPs may also be installed.

Runner stands for Runner launcher

It's a genuine process which runs when you execute the tool called Websecurify Scanner

Great for school computers which blocks .exe files. A way to get around security features and play games at school by converting .exe files into .jar

Best practices for resolving runner issues

A clean and tidy computer is the key requirement for avoiding problems with runner. 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.
