Error code 703 (0,5)

Recommended Posts


Had the above error code this morning when trying to run malwarebytes. Read a few of the other posts here and ran below as suggested by AdvancedSetup on Flapjacks post.


Seems to have respolved the problem as I can now run Malwarebytes - question is do I need to do anything else to make sure it doesn't crash again.

I'm running AVG. Search & Destroy with tea timer enabled, spyware guard and spyware blaster

Many thanks

Greetings and welcome Norton <_<

I'd recommend that you exclude the following files from your antivirus to avoid any potential conflicts:

For Windows XP:

  • C:\Program Files\Malwarebytes' Anti-Malware\mbam.exe
  • C:\Program Files\Malwarebytes' Anti-Malware\mbamgui.exe
  • C:\Program Files\Malwarebytes' Anti-Malware\mbamservice.exe
  • C:\Documents and Settings\All Users\Application Data\Malwarebytes' Anti-Malware\rules.ref
  • C:\Windows\System32\drivers\mbam.sys
  • C:\Windows\System32\drivers\mbamswissarmy.sys

Note: If using a software firewall besides the built in Windows Firewall you'll need to exclude them from it as well

If you're using an operating system other than XP (ie Vista or 7) please let me know as the paths to the files are different. Also let me know if you are running a 64 bit version of one of those operating systems.
