Qgis-bin.exe - System Error

Qgis-bin.exe - System Error

I'm running QGIS 2.8 Wien on Windows 8.1. I got this error:

The program can't start because qgis_core.dll is missing from your computer. Try reinstalling the program to fix this problem.

I got the same error last week, uninstalled and reinstalled QGIS and it worked. But there must be a better way to fix the error than reinstalling QGIS every time it bombs out.

It is probably due to the antivirus software. QGIS works fine at first but this problem arose after a reboot. Try to disable the antivirus software and try again but please do so at your own risk.
