Windows 7: BSOD with several Chrome windows, error 3B (C0000005, ...

Not going to be necessary. I looked at this a little yesterday and this morning. Unfortunately I don't have anything conclusive, but I do have a very strong hunch. Keep in mind that I'm still relatively new to debugging (have been diving in head first last month or two) so maybe a veteran might be able to dig a little deep than I have.

I believe what's happening is the Rapport software that is installed is corrupting Avast's page table. Likely in a buffer overflow, but I've not confirmed that and have no evidence of it (yet). The fact that the two processes and their stack frames are consistent with the crashes makes me believe they're tripping over one another. The "trip" always appears to happen during a usermode interaction that makes a kernel call. I'll provide some of the code I went through to hopefully paint a thorough picture for you.

With all that said, I would start by uninstalling the Rapport software and monitoring the situation. My bet is that the problem goes away.

Code:

Thanks for looking into this!

It makes sense that it could be Rapport. The one situation that I reproduced that caused the crash was logging into a site. Some of the sites use Rapport, I can't remember which at this point, and I neglected to write down which site it was, but it might have been one that used it. The problem is pretty intermittent--it can come up several times in a day and then not for a week, so it could take a while before I know for sure.

I hadn't mentioned this before, but it is something else that has been coming up for about the same period, and just happened again: Windows Explorer crashes intermittently. Most of the time it just restarts itself, but occasionally I have to restart the machine. Do you think this could be related???

It's probably unrelated because the explorer crashes are happening in usermode. Aside from looking at event logs (eventvwr.msc) and any other various logs explorer.exe keeps track of, the only other method of debugging this would be to attach a live debugger and wait until the process terminates.

OK, it's been a week and no BSODs. I am marking this solved. The only thing I changed is to remove Trusteer Rapport, which is apparently used by some 50 banks on the server end as well as recommended for their users. I told Trusteer about it, and with luck it will be fixed in a future version. Meanwhile I am considering a dual boot or Live CD/USB Drive.

It seems the antivirus and other protective software like Trusteer, as well as the OSs themselves are in a sort of core wars to get to deeper levels of your system in order to attack or protect the system. It's not surprising that they end up stepping on each other in the kernel--it's more surprising that often the systems keep working.
