I've been using ZASS for a long time, but for the first time I'm getting a Zone Alarm Security Alert:

SUSPICIOUS BEHAVIOR

Microsoft Windows Search Indexer is trying to launch C:\Windows\System32\SearchFilterHost.exe, or use another program to gain access to privileged resources.
Application: SearchIndexer.exe (View Properties show it on C:\windows\system32\)

Any thoughts on what I should do? I got this alert right after a reboot. Thanks.

Operating System:Windows Vista Home Premium
