BO:Writable BO:Heap

Kindly help me on this, When I open any video file my McAfee AV 8.5 catches the following.
Blocked by Buffer Overflow Protection C:\WINDOWS\Explorer.EXE:KERNEL32.GetProcAddress BO:Writable BO:Heap
It does not let me clean, delete, or quarentine the file. I started my computer in safe mode then ran a scan using the AV as well as AVG and both came up with nothing.

I hope anyone could help me on this.

Thanks, K_Jezz
