Since installing BES 4.0 SP3, we now get this message periodically, esp. at logon:
---------------------------
Microsoft Visual C++ Runtime Library
---------------------------
Buffer overrun detected!
Program: C:\Program Files\Symantec AntiVirus\Rtvscan.exe
A buffer overrun has been detected which has corrupted the program's
internal state. The program cannot safely continue execution and must
now be terminated.

OK

On Symantec's support boards, there are a number of new threads about this. The upshot is that Symantec believes it's BES-related.
Here's a representative thread.
Here, it has only happened on our BES server, and only since installing 4.0 SP3/Exchange (we were on 4.0 SP2/HF2 before SP3). We are running BES 4.0 SP3/Exchange and SAV CE 10.0.1.1000. There's a newer SAV version but we haven't deployed it yet (haven't finished deploying the last one!)
Apparently SAV 9.x doesn't have the problem. Symantec seems to be zeroing in on the QuickScan feature, which is new to 10.x, and that would explain why we most often see it at logon.
This thread describes disabling QuickScan. I haven't tried this yet.
Didn't get any hits here or on BlackBerry.com searching under "Symantec" "AntiVirus" or "SAV" so I thought I'd raise a red flag.
