Yup, that is what I'm going to do. Just has me curious since this is Windows defender we are talking about. It's not some fly by night AV. It's what pretty much most people are using especially w/Win 8.1 so I wonder why it is behaving this way. But yes, for now, I will exclude it. Thanks.

Looks like this might be some kind of bug/issue with Windows 8.1. I found this here. I asked a question there about it: https://social.technet.microsoft.com/Forums/windows/en-US/7471ef35-4453-4cf5-9c94-857ece5772e3/feedback-some-problembug-in-windows-defender-410209-client?referrer=http://social.technet.microsoft.com/Forums/windows/en-US/7471ef35-4453-4cf5-9c94-857ece5772e3/feedback-some-problembug-in-windows-defender-410209-client?referrer=http://social.technet.microsoft.com/Forums/windows/en-US/7471ef35-4453-4cf5-9c94-857ece5772e3/feedback-some-problembug-in-windows-defender-410209-client?forum=w8itprosecurity

Anyway, I excluded it and it seems to be working fine - thanks.

Okay.. one question. Do you know why it is showing this missing startup entry? If I look in Ccleaners startup, it shows the windows defender entry: Yes HKLM:Run WindowsDefender "%ProgramFiles%\Windows Defender\MSASCuiL.exe" I guess i just want to make sure it is actually running since ccleaner is stating it is missing as a startup entry after a reg scan.

Hi. I just clean reinstalled Windows 8.1 after getting sick of Windows 10 breaking everything after a feature update. Everything is great - system is fine. There is one issue that comes up when i do a registry scan with Ccleaner. It finds this: Missing Startup Software "%ProgramFiles%\Windows Defender\MSASCuiL.exe" HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Run If i delete/fix the entry using Ccleaner, and restart and do a reg scan again, the issue comes back If seems to refer to Windows defender. If I look in my startup (through task manager), it shows the entry Masacuil. If i do the scan and delete it, this masacuil entry will disappear but then come back on a restart (and show again in Ccleaner). Can i fix this? I seem to recall it usually shows Windows defender (not msascuil) when I look at the startup entries in task manager. Windows defender works fine otherwise - no issues. Thanks for any help.
