Hi mormegil27,

Try the offline installer for Bitdefender Total Security 2015:

http://forum.bitdefender.com/index.php?act...amp;qpid=248138

Are you by chance running Malwarebytes? If so, there seems to be an interaction between the two, or somehow caused by one or the other, that

causes BSOD's. If you are running Malwarebytes, then configure it so that "Malicious website protection" is disabled. (This just disables real-time

protection; you can still run full scans by invoking Malwarebytes manually.) You can do this by right-clicking on its icon in the system tray, and

unchecking the "Malicious website protection" menu item. Just make sure to disable it in the preferences as well, or when you restart Windows,

Malwarebytes will start again with "Malicious website protection" enabled again.

From what I've been able to piece together:

Bitdefender 2015 + Malewarebytes = Fine

Bitdefender 2015 + Malwarebytes = BSOD's, but I don't know why, and it's not necessarily reproducible on all machines. For instance, I have

Bitdefender 2016 and Malwarebytes Premium (fully updated to the latest version) running without problems on my Surface Pro 3. It used to cause

BSOD's. I don't know why it doesn't now. Perhaps it has something to do with running an insider build of Windows 10 that I don't have on my

Surface Pro 4 yet.

The Surface Pro 4 is another story. I have Bitdefender 2016 and Malwarebytes installed on it. Unless I disable "Malicious website protection," it will

pretty reliably lead to roughly one BSOD per day of heavy use. When I reverted to Bitdefender 2015, the BSOD's stopped. I then reinstalled

Bitdefender 2016, and the BSOD's started again. I disabled "Malicious website protection" in Malwarebytes, and the BSOD's stopped.

I wish that I could narrow it own further. My best guess is that whatever is happening, it's low-level driver-related, specifically related to TCP/IP

networking, which possibly suggests something to do with the Bitdefender firewall. I don't know this for a fact yet, but if it's true, I believe that if

you disable the Bitdefender 2016 firewall and enable the Windows 10 firewall, your BSOD's will stop.

If you find anything else out, please let us know by posting here again. Currently, the best evidence that we have--which is anecdotal and based on

scattered posts in various forums by users experiencing BSOD's with Bitdefender 2016 (and usually Malwarebytes) installed--suggests that Bitdefender

2016 is the ultimate cause of the BSOD's through a mechanism that we don't understand yet.

Good Luck,

Steve

Also, assuming the problem is a Malwarebytes conflict, how will I know when this conflict is resolved? Does Bitdefender perform the same service as Malwarebytes "Malicious website protection"? Or am I losing functionality? I would prefer to have all my products that I have paid for work properly (as anyone would).

If anyone knows the solution to the 2015 reinstall issue I mention in the above post (i.e. auto-reinstall of 2016, and whether I can use 2015 having not owned it), please don't forget to post about that.

Thank you!

Hi Guys,

It's definitely the case that if you're running Bitdefender 2016 and Malwarebytes Anti-alware, disabling "Malicious Website Protection" in the latter will stop your BSOD's.

mormegil27, Bitdefender 2016 will keep BSOD'ing once every day or so until the above is done in Malwarebytes. Yes, you can install the 2015 version of Bitdefender using the offline install link that I mentioned in an earlier post in this thread. It links to an article that, itself, contains a bunch of different links. Just find the right one for Bitdefender 2015, download it, and install it (after uninstalling 2016). Everything will work, and you can re-enable "Malicious Website Protection" in Malwarebytes.

If I can find time within the next few days, I'll try to contact someone at Malwarebytes, explain the details, and see what they'll do about it. The bottom line is that Bitdefender 2016 and Malwarebytes Anti-Malware are incompatible. Something is happening with drivers that it interacts with or modifies that causes BSOD's. At least we have a workaround. I was going crazy when this was happening on both of my Surfi (the plural form of Microsoft Surface ).

Good Luck,

Steve

Ok, here is a post about how to exclude Malwarebytes from Bitdefender, not sure about the reverse.

https://forums.malwarebytes.org/index.php?/...h-malwarebytes/

Excluded Bitdefender from Malwarebytes, and Malwarebytes from Bitdefender, but the crashes continue.

Attempted to install Bitdefender 2015 instead. It refuses to recognize my subscription, likely because I never owned Total Security 2015, I only own 2016.

Please help if anyone is still looking at this, particularly admin. What do I do? I should be able to use both products together. Possible solutions:

(1) Fix for Total Security 2016 + Malwarebytes?

(2) Give me access to Total Security 2015?

(3) Downgrade my subscription of Total Security 2016 to one of the lesser versions, such as Anti-virus Plus 2016, which might actually work with Malwarebytes? I don't actually care which version it is, I just want both programs to work together.

Are there Bitdefender admins/engineers/employees who actually read these forums and can directly help me?

Thank you!

What's the problem your having?

I am not alone in experiencing the problem with latest update to Malwarebytes Premium See here

I opened a Bitdefender support ticket on this.

There was no problem with BDTS 20.0.26.1418 and the previous release of Malwarebytes 2.2.0.1024. Note that I had them installed together for only a couple of days before the update to MBAM The proiblem began immediately after the update to MBAM Pro 2.2.1.1043.

Hopefully this gets resolved sooner rather than later.

Ditto on the BSODs upon 2.2.1.1043. I've removed MBAM Premium.

No problems here with that combination.

I too appear to have this Bad Pool Header problem which causes Windows to gather information and restart. Never had this with previous BitDefender Total Security / Malwarebytes Premium combinations.

The problem only surfaced when I upgraded to BitDefender Total Security 2016.

I do not wish to stop using either programme as both offer excellent protection. I have been using BitDefender for a couple of years now and MalWarebytes since its introduction to the marketplace.

It would be great if both company,s techies could get together over a glass of wine and sort this out as their programmes compliment each other nicely.

Hello All,

With MalwareBytes installed if I try to add MalwareBytes to the trusted applications in BitDefender the add button is not available, ie it is not blue so I cannot add MalWarebytes as a trusted application. When I uninstall MalWarebytes the add button becomes available, ie is blue. Any idea what is going on.

I like both MalWarebytes, which I have used without difficulty since its introduction to the market and BitDefender, a more recent addittion to my security setup.

I must soon decide which programme to keep and which to discard. I know MalWarebytes will work fine alongside other security suites and appears to conflict only with BitDefender. This would appear to be a massive conflict given that BitDefender will not even allow MalWarebytes to be treated as a trusted appklication.

Any assistance would be appreciated.

Hi,

If the BSOD still occurs after reinstalling Bitdefender 2016 with the latest kit from Central, please let us know what seems to be the scenario that triggers it? Are you using a specific program at that time? What action are you performing in Windows and what are your MBAM settings? Did you change anything in MBAM or did you leave the default settings? What seems to cause this crash?

It will also help to have a complete memory dump (not minidump):

http://www.bitdefender.com/support/How-to-generate-full-memory-dumps-1169.html

And a Bitdefender support tool log:

right click on the file supporttool.exe from the folder C:\Program Files\Bitdefender\Bitdefender 2016 and choose 'Run as Administrator' from the menu. We need the archive BDSP_ that appears on your Desktop at the end.

Please upload them to a file transfer website such as www.sendspace.com and reply with the download link, together with the response to the above questions.

Thank you in advance for your cooperation.

For the time being as a workaround you can disable the Malicious website Protection from Malwarebytes

It may differ with other versions of the product. I'm using Total Care 2016 now, and it's in the Firewall module.

Awesome, I hope that works for you while the developers come up with a permanent solution.

Hello all,

The blue screen reported in this topic was corrected in the latest Bitdefender 2016 build version released today.

Please turn back on Block port scans in the network from Bitdefender firewall then click Update on the main interface. Wait until the update process completes, then click the top right menu and select Events in the drop-down menu. Locate in the list of Update events the event asking to reboot the computer. Click on it and then click Restart Now button in the displayed details. If you don't see the notification to reboot the computer in Events simply restart Windows.

After Windows reboots right click on the Bitdefender icon from the system tray (the area near Windows clock), choose About and look at the Product Information number. It should be 20.0.29.1517.

Please accept our sincere apologies for the delay in fixing this bug. Those of you who also contacted Bitdefender support via e-mail will be notified about the fix shortly after this post is live.
