BSOD occurs random times and when running Toshiba NTI Backup Now app

Hello npotti.

The BSODs are caused by intel RST driver.

Code:

Uninstall McAfee Using McAfee Removal Tool. Use Microsoft Security Essentials as your antivirus with windows inbuilt firewall, and free MBAM as the on demand scanner.
Download, install and update those, and then run full system scans with both of them, one by one. Scan the system for possible virus infection with the following programs, too.

• Anti-rootkit utility TDSSKiller
• Windows Defender Offline
