I want to stop/kill UpdaterUI.exe. It has over 23million IO Reads in 16 days. That is 16 reads/sec.

My question is...

  1. Is there any formal way to disable/stop it? E.g. Option/Registry/etc
  2. If no, is there any harm if I just kill it in Task Manager?

What program/application does UpdaterUI.exe comes from? Can you link us to its homepage? – badp Sep 3 '10 at 10:52

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.

+1 And, if you decide to switch AV, and performance is a concern, check out the performance (and other) tests over at AV Comparatives for some help before you install something. – DMA57361 Sep 3 '10 at 11:46
+1 Though I would pull AVG off that list. They're no longer as lightweight as they used to be, especially compared to Avast and MSE. – Tofystedeth Sep 3 '10 at 14:40
@Tofystedeth: I have personally moved away from AVG to Avast, but some people swear by it. – harrymc Sep 3 '10 at 14:46
