Event Viewer - Found two problems



I've found two problems in the Event Viewer on my newly installed Windows 7 Ultimate x64.
I had some Peer Networking problems too but I fixed that from a post here on Windows Forums. :)
But I don't know how to fix these two problems.

First one is a warning (Logname: Application | Source: User Profile Service | EventID: 1530 | User: SYSTEM):
Windows detected your registry file is still in use by other applications or services. The file will be unloaded now. The applications or services that hold your registry file may not function properly afterwards.

2 user registry handles leaked from \Registry\User\S-1-5-21-3805051128-2016929007-1870689896-1000:
Process 1524 (\Device\HarddiskVolume3\Program Files (x86)\Avira\Antivirus\avguard.exe) has opened key \REGISTRY\USER\S-1-5-21-3805051128-2016929007-1870689896-1000\Software\Microsoft\Windows NT\CurrentVersion\Winlogon
Process 1948 (\Device\HarddiskVolume3\Program Files (x86)\Avira\Launcher\Avira.ServiceHost.exe) has opened key \REGISTRY\USER\S-1-5-21-3805051128-2016929007-1870689896-1000\Software\Microsoft\Windows\CurrentVersion\Uninstall

Second one is an Error (Logname: Application | Source: WMI | EventID: 10 | User: N/A):
Event filter with query "SELECT * FROM __InstanceModificationEvent WITHIN 60 WHERE TargetInstance ISA "Win32_Processor" AND TargetInstance.LoadPercentage > 99" could not be reactivated in namespace "//./root/CIMV2" because of error 0x80041003. Events cannot be delivered through this filter until the problem is corrected.

Please advise and tell me what you need to know more about to help and I will gladly post.

Thank you!
