BSOD when returning from sleep and sometimes randomly. 0x000000E1

Welcome

Problematic software:

Code:

Start Menu\Programs\McAfee	Public:Start Menu\Programs\McAfee	Public

Please uninstall McAfee, it's a known cause to BSODs

I and many members on our forum recommend Microsoft security essentials with
a great combination of Malware Bytes.

→ Microsoft Security Essentials - Free Antivirus for Windows
→ Malwarebytes - The Free version
→ Good and Free system security combination.

Run a full scan with both (separately) once downloaded, installed and updated.

In addition, Run this tool and delete anything it finds:
→ Anti-rootkit utility TDSSKiller

Run the system file checker for repairing corrupted windows files
