Windows 7: random BSOD - W7 pro 64bit - no idea as to why

Microsoft Windows 7 Professional 64 bit 7601 Multiprocessor Free Service Pack 1
 
 

Ok, I think I managed to identify the driver responsible for my OS freezing.
I've run he driver verifier separately on the different drivers, and this is the one my OS froze up on: bdfm.sys version 0.5.1847.1196 built by WINDDK. It's a Bitdefender driver: I use the 2011 Internet security suite.

What do you think?

In case that is the responsible driver, can anybody suggest a good antivirus suite, perfectly compatible with Windows 7 64bit?
Thanks.

I've reluctantly installed the 2013 edition of Bitdefender Internet security. I hate it already (for reasons I'm not going to bore you with), but the damn driver is not in the system anymore.
I've had a couple of crashes (FIrefox and Thunderbird), but so far no blue screens (and I've also re-installed Anydvd HD again - yesterday my pc crashed four times in a row, after I installed Anydvd HD).
In case of new BSOD, I'll post an update.

Free AV solutions are pretty good nowadays, with MSE (Microsoft Security Essentials) being top dog atm. Though if you want a pay one that has more options and features, I've been hearing frequently that ESET has been most impressive.

When you ran Memtest, did you run it for only one pass? Make sure to do it overnight so that it'll run several passes of all tests on all your RAM. Most RAM issues do not manifest on the first couple passes but after consistent usage they start flaring up.

You'll also wanna run the rest of the Seatools tests (besides Advanced). Long generic doesn't show up all problems, neither does any of the other tests, but altogether they comprehensively test all manner of functions on the drive.

Other than that, we'll just have to see how it goes for now.

I ran Memtest for four-five passes, no errors.
As of today, after I've installed the 2013 edition of Bitdefender internet security, I've had non more BSOD (though I'd rather not being overtly optimist just yet).

Thanks a lot for the ESET suggestion, I'll check it out. I was thinking about installing Kaspersky, but I used that a couple of years ago and had some problems too (can't recall what sort of), so I wouldn't mind trying something different.

If I don't get any more BSOD for a reasonable time, I'll mark this post as solved.
Thanks again.

I personally haven't had much problem with Kaspersky. They are very effective with rootkits, for one, and have one of the better AV engines. Can't say much about their stability though (be it good or bad) since I haven't used it long enough to determine that.

Glad to hear the BSODS seem to have puttered out. I figured older AV that's pre-Windows 7 would definitely cause trouble, and this would be no exception to that rule. It's often necessary to upgrade AV software to accomodate a new OS, even if it would mean purchasing an upgrade.
