Hi,
I just got a BAD_POOL_HEADER blue screen; I suspect it was avast. I accidentally ran one of my programs in sandbox, and it crashed, so I re-ran it, hoping avast would ask me again, but avast ran it in the sandbox again. I tried this a few more times and got a BSoD. I uploaded the dump to avast ftp, it's named MEMORY_xqrzd.7z.
On a side note, I think theres something wrong with avast's sandbox, since the program was a simple app that didn't do anything the sandbox should watch. This seems to happen on most C++ apps compiled with Visual Studio.
