DefenseWall "shatter" in event log

[kvernick]

What is a the event type, shatter, listed under the DW event log? Eudora email client is listed as trying to talk to multiple processes it should probably have no honest business talking to. For example, listed under Eudora:

Attemps to send message 3E0 into the window of the process C:\Program Files\Symantec Client Security\Symantec AntiVirus\VPTray.exe.

And many others, including explorer and apparently all the security programs. I think acrobat was doing something similar the other day.

Should I be worried about this? If you google shatter attack, it doesn't sound good...

That's refferring to a "shatter attack"

I would assume most of what you are seeing is harmless, a process sending some sort of message to another process. If it is harmful, well DW has stopped it

This message is wildly used by meny programs, so, within the next, 1.74 version, this message number will be disconcontinued from blocking as shattered.

OK, that doesn't sound bad (probably). Thanks.
