I get the unexpected kernel mode trap ONLY when my children use their account. I suspect it is due to the Family Safety program. But Microsoft community say it is due to Avast.
Got a BRAND NEW computer. SAME problem. ONLY with kids Family Safety Accounts. Without the Family Safety Account set, it NEVER crashes.
My both my older Dell XPS 18 and brand new Leveno Flex 20 runs on Windows 8.1, and Sony Tap 20 runs on Windows 8.1 pro.  ALL THREE machines have the same problem. ONLY with Kids Family Safety Accounts. ALL OTHER ACCOUNTS NEVER CRASHES.

I am experiencing this error on Windows 8.1 as well, on children accounts with Family Safety on.

BTW, my Windows 7 Pro Asus slate does not crash. even  with my family safety turned on and Avast installed.

My search in windows community have the same problems. People found solution by uninstalling Avast.

Re: unexpected kernel mode trap -- Problem with AVAST Pro, not in AV Free!
« Reply #5 on: October 20, 2014, 12:13:27 AM »
I had the same problem until yesterday, but was able to pinpoint it to AVAST Pro only. It does not happen with AVast Free.

Situation: Windows 8.1 Pro, one kids account with Family Safety on (incl. Web filtering), another (admin) account without Family Safety. After Installation of AVAST Pro 30-Day-Trial (on oct 6th) I had spurious BSOD Unexpected_Kernel_Trap as described above (up to 4 a day) ONLY if using the kids account.

On a 2nd laptop with identical hardware and software, but using AVAST FREE, there were no problems at all.

Using Microsoft "Driver Verifier" with the settings as described in http://www.techsupportforum.com/forums/f299/bsod-0x7f-ntoskrnl-exe-153fa0-whie-playing-game-870850.html , I was able to provoke the BSoD every time I logged in to the kids account. It never happed with the admin account.

So I downlevelled the Trial-Version of AVAST Pro back to AVAST Free (using the builtin downlevel feature), and the BSODs were gone. So that is the solution for me - sticking to Avast Free.

@AVAST: This should give sufficient information to track down this bug in co-existence of MS Family safety and Avast Pro in the current version (oct 6th - Oct 19th)

I'm also experiencing this problem  under the same conditions. It appears that the answer from Microsoft is to switch off Avast (or AVG) and use Windows Defender. see the following thread... http://answers.microsoft.com/en-us/windows/forum/windows8_1-security/family-safety-causes-unexpectedkernelmodetrap-on/54a43bae-984f-4151-8987-ac511aaa70cc?page=1

Please will you guys urgently look into this matter?

The problem still hasn't been resolved . Have bought 3 Premier licenses but due to Family Safety conflict can't use 2 of them effectively. Come on guys - do something to solve this problem  asap. One year later no solution found?

Best you submit a ticket: https://support.avast.com/Tickets/Submit

Ticket system has changed somewhat:
- simplified Submit ticket form - no more asking about the product, platform etc. Just write us your message. http://support.avast.com/support/tickets/new

See https://forum.avast.com/index.php?topic=177577.0 for more information. I don't know how that would effect submission of possible FPs though.

OK Just use the Spanner and Screwdriver and the next window gives you the option to attach a file.
Windows 10 Home 64bit/ Acer Aspire F15/ Intel Core i5 7200U 2.5GHz, 8GB DDR4 memory, 256GB SSD, 1TB HDD/ avast! free 21.8.2487 (build 21.8.6586.691) UI 1.0.666/ Firefox, uBlock Origin, uMatrix/ MailWasher Pro/ Avast! Mobile Security

It depends on how you look at it, but you can also say that MS still hasn't solved the problem.

Sure... If you care stops because it has no fuel... Get a new car that has fuel... :(

Let's see...
No problem - family safety + avast + Windows XP
No problem - family safety + avast + Windows 7
No problem - family safety + avast + Windows 10
Problem - family safety + avast + Windows 8.x

Guess where the problem really is....
