A. The bug/issue

  1. What you did: used computer normally- I was typing in notepad. Had recently checked to enable advanced protection, but was finishing up some code before restarting.
  2. What actually happened or you actually saw: Every character in every open document turned into squares, the time in the bottom right was replaced by a couple of lines of Chinese characters, almost every application I had open at the time said exception 0x1 had occurred (I believe that’s memory?), clicking on shortcuts didn’t do anything and I couldn’t open any programs, dllhost.exe took up 2gb in task manager, and when I tried to dump it to disk windows said it couldn’t find drive c, and when I clicked restart the attached error message popped up- clicking ok did nothing, so I clicked the x and got a BSOD. Memcheck reports all good.
  3. What you expected to happen or see: none of the above :-p.
  4. How you tried to fix it & what happened: nope
  5. If its a software compatibility problem have you tried the compatibility fixes (link in format)?:
  6. Details & exact version of any software (execpt CIS) involved (with download link unless malware):
  7. Whether you can make the problem happen again, and if so exact steps to make it happen: nope
  8. Any other information (eg your guess regarding the cause, with reasons): comodo driver overwrote memory it shouldn’t have, started a cascade of awful

Hi zxctypo,

Can you please attach the zipped version of the .dmp file as it contains more info that is needed to troubleshoot this issue.
From first look at it it doesn’t blame CIS components.

First time I found problem when mTorrent and one of trusted applications were working. BSOD appeared again when i used different applications for various periods. I saw it three or more times and used BlueScreenView utility for help.

May be i am making mistake, but i think trouble is in QoS service or cmdguard.sys driver, because i have last nVidea driver updates/ ???
Some forums writes that conflict of firewall and nVidea drivers is a reason
http://forum.ixbt.com/topic.cgi?id=4:92071
Another ones writes that conflict of DEP(Data Execution Prevention) with firewall causes this BSOD. I will try to turn off DEP and watch…
And re-installing network adapter drivers led to nothing. (It is one way of solving problem, i saw in forums)
Thanks for your help… (And i could not add screenshots, clicking on insert image… why?)
