Can cause lots of HDD access after starting your computer causing everything to run slowly.
It slows down startup, and ironically prevents NetZero's exec.exe from loading on my PC. It should be disabled via msconfig for performance reasons.

Best practices for resolving nzspc issues

A clean and tidy computer is the key requirement for avoiding problems with nzspc. 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 repairing of your installation or, for Windows 8 and later versions, executing the DISM.exe /Online /Cleanup-image /Restorehealth command. This allows you to repair the operating system without losing data.
