BSODs on Samsung laptop probably caused by Avast!

Hello!

I use Avast! Free Edition latest version and updated on all my desktop machines with no problems whatsoever, except for my Samsung NP300E52-S02PT laptop in which I get random BSODs. Sometimes the laptop can stay 3 or 4 days without bsod’ing, other times just a few hours.
The crashes have happened when the computer is on heavy work, idle in desktop, watching videos using flash/silverlight, etc…

I posted topic in sevenforums.com with my laptop information and some memory dumps:

A user replied saying that the drivers aswSP.SYS and aswSnx.SYS may be causing the crashes.
I uninstalled Avast! on 4/September/2013 and the computer has since been running 24 hours a day and no BSODs … (today is 11/Sept)
He also advised me to install MS Security Essentials which I didn’t because I wanted to check if avast! was really causing those crashes.

So what is wrong? My other machines don’t have any crashes and some are working 24/7. Could it be a memory issue? I didn’t run any exhaustive memory test software yet but I will do it in the next few days.

Thanks in advance.

what AV did you use before avast?
did you uninstall it before installing avast?

run OTL and attach diagnostic log. http://forum.avast.com/index.php?topic=53253.0

I didn’t use any anti-virus before Avast.

I ran OTL and I attached the files OTL.txt and and Extras.txt to this post.

Thanks!
