This info applies to Logitech QuickCam driver version for the QuickCam Pro 4000. As Josef S says, ISStart.exe is loaded on startup under the name LogitechVideoRepair. I have run the Logitech QuickCam software, including capturing images and video using QuickCapture successfully with ISStart.exe at least not loaded on startup. The only anomaly that I noticed was that I was no longer able to change the webcam's settings.
Addition to previous comment: I was no longer able to change the webcam's settings *in QuickCapture*. I had access to all the normal audio and video settings through all other programs

Best practices for resolving ISStart issues

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