I want to stop/kill UpdaterUI.exe. It has over 23million IO Reads in 16 days. That is 16 reads/sec.
My question is...
- Is there any formal way to disable/stop it? E.g. Option/Registry/etc
- If no, is there any harm if I just kill it in Task Manager?
updaterui.exe usually belongs to the McAfee Enterprise application and should reside somewhere in the McAfee installation directory, normally in a subfolder of "C:\Program Files". In this case, it's a required component for your security.
If it resides anywhere else, then it's possibly a virus.
As companies such as McAfee are adding tens of thousands of virus descriptions daily to their virus database, then naturally lots of I/O is required to update the database. It's then quiet normal for this process to heavily use I/O.
If you think McAfee is slowing down your computer (and you won't be the first), uninstall it and find a better and more efficient antivirus. There are currently several excellent ones that are free for personal use, such as Avast, Avg, Avira AntiVir, Microsoft Security Essentials.
