BSOD caused by aswSP.SYS
« on: October 11, 2010, 05:20:58 PM »
Woke up this morning and turned my computer on. To my surprise my system crashed, giving me a BSOD. I was finally able to log in after a second attempt, opened BlueScreenView and received the following:

Mini101110-01.dmp   10/11/2010 9:32:51 AM   BAD_POOL_CALLER   0x000000c2   0x00000007   0x0000110b   0x08900006   0xae3e0b88   aswSP.SYS   aswSP.SYS+1cb50   avast! self protection module   avast! Antivirus System   AVAST Software   5.0.677.0   32-bit      C:\Windows\Minidump\Mini101110-01.dmp   2   15   6002   

I don't recall Avast ever causing a system crash before. Incidentally I upgraded to version 5.0.677 about a week ago.

Has anyone experienced this problem? How did you resolve it? Thank you.

Would you happen to have any other security software installed on this pc?

@zubina,

thanks for minidump. This bug was already fixed in the internal version – I've recompiled it against fixed version of the aswSP.sys driver, please follow these steps:
1) Download patch for:
         - 32-bit OS: http://public.avast.com/~kurtin/public/sp_01/x86_patch.zip (100kb)
         - 64-bit OS: http://public.avast.com/~kurtin/public/sp_01/x64_patch.zip (70kb)
2) Stop avast self-defense (avast settings -> Troubleshooting page)
3) Copy *.sys and *.sys.sum to \Windows\System32\Drivers and \Program Files\ALWIL Software\Avast\setup\inf folders (overwrite existing) [*** or backup/rename original files]
4) Re-enable avast self defense
5) Restart the computer

See my other thread "aswSP.sys BSOD" started today for another BSOD related to aswSP.sys, it does not seem to be the same crash, at least not in the same part of the driver.
