Since I downloaded Norton™ Internet Security For Mac via Comcast in mid 2011, Safari crashes several times a day. Each time the error message indicates that the WDICEngine plug-in is the cause. The following is my current configuation:
Mac OS 10.5.8
Safari 5.0.6
in /Library/Application Support/Symantec/WebFraud/WCIDEngine.bundle
is version "WDICEngine 3.1.3f4"
