Blue Screen. Issue with atheros network card. ndis.sys & l1c62x64

I'v had a couple blue screens this week on Tuesday and Thursday. I've gotten error messages for both ndis.sys and l1c62x64. This has been a recurring issue for a while, but it recently started occurring very frequently.

caused by drivers using improper addresses.

Uninstall Symantec for testing purpose.

Microsoft Security Essentials is recommended from a strict BSOD perspective, compatibility & stability compared to other internet security software. Malwarebytes is a great combo to MSE. They are free and lightweight.

Also uninstall your existing Antivirus software before you install MSE.

Good and Free system security combination.
