The slow shutdown issue with the 1517 warnings in the Application event log are still present with this newest version when the two system tray icons are merged.
I never imagined that the two icons merged has anything about this… but, as you say…
I have tons of Windows Events too, a lot related to Opera skins, Real Player skins… I have not opened these applications today, or yesterday, but tons of Events were registered…

can I check? Are you reporting that this problem was one continually encountered with the previous release and continues with this new release, or is this a previously fixed problem that has re-surfaced with the new release.
Just out of interest - are you using a firewall and if so, which one?
Hello,
I am using this Microsoft tool (User Profile Hive Cleanup Service) to prevent these 1517 warnings from occurring, works pretty good for me.
I was not having any 1517 warnings from avast usage, but from several other apps on my PC.
Here is link for the tool if you want to try it out:

alanrf,
This problem was reported with the last version of avast. I couldn’t believe it but when I tried it it was true. If you split the icons, the warnings dissappear and the PC shuts down faster. It was never fixed. I don’t think it was even acknowleged by the avast team. Can the avast team comment?
I used user profile hive cleanup service but I don’t want another service running on my PC permanantly. This tool was mainly designed to help troubleshoot these errors, not to run all the time.
As I understand the profile hive cleanup will report the keys and services responsible for the 1517 events.
I think that a “one off” run to produce an up to date list in the two different conditions (shutdown with icons combined and shutdown with icons split) in version 731 would be a valuable piece of diagnosis for the avast team.
If many others were encountering this same problem with any regularity then it’s likely that we would see more reports.
I have the icons combined and only see this event very sporadically. The only time I have seen them regularly was on an update to ZoneAlarm earlier this year.
The profile hive cleanup reported a svchost service. I contacted the author about this and she was unable to determine what specifically caused it.
