Crashes point to Kaspersky, Norton Backup, and/or ShadowDefender. Start removing these programs one by one and determine which is causing the crashes.

Removal tool for Kaspersky Lab products will help with removing Kaspersky.


If you remove Kaspersky, I recommend either of these:

• Microsoft Security Essentials - Free Antivirus for Windows coupled with Malwarebytes. Do not start the free trial of Malwarebytes. Just use the standalone version, update it, and scan your computer once a week with Malwarebytes and with Microsoft Security Essentials.
  
  
• Good and Free system security combination.

Ok i will un-install them 1 by 1, ill go first on SD.

Could you tell me why you suspect one of these softwares caused the BSOD in my computer?

Thanks for the link you provided very useful tips.

Kaspersky was the process running during one of the crashes. The other two had drivers that were in the stack during the crashes or directly blamed as probably caused by ****.sys where the asterisks were replaced by the driver name associated with each of the two programs I mentioned.

The above is Kaspersky...


The above is ShadowDefender...

One of your images had symsnap.sys as the cause. StorageCraft Volume Snap-Shot or Symantec/Norton Backup Exec...

Seems fine now when i uninstalled SD. Is there any other way to prevent this crashes when SD is installed in my computer? Because i want to use it.

It may be a conflict between Kaspersky and ShadowDefender. It may also have been a corrupted installation of Kaspersky or ShadowDefender causing issues. I assume ShadowDefender is now removed.

• Remove Kaspersky as I suggested before.
• Then, download a fresh installer for Kaspersky and install it.
• Then install ShadowDefender from a freshly dowloaded installer for it.
• See if you get crashes.
• If so, remove Kaspersky with its uninstall tool and replace it with MSE and see if you get crashes.

Useful links in the above process:

• Removal tool for Kaspersky Lab products
• Microsoft Security Essentials - Free Antivirus for Windows
• Good and Free system security combination.
