How do I render a buffer overflow message by my security  center, cause I know it aint good to keep re-appearing. Heres the message:

 

McAfee has automatically blocked a buffer overflow.

Details
Detection:
File: C:\WINDOWS\Explorer.EXE

More Info
Buffer overflows occur when suspect programs or processes try to store more data in a buffer (temporary data storage area) on your computer than its limit, corrupting or overwriting valid data in adjacent buffers.

If you do not recognize this activity, McAfee recommends that you continue to block it. If you recognize this activity, trust it in the future.

 

It has something to do with movie files I keep bringing onboard, like when I open my "My Videos" in my documents where I store all my video files. Any suggestions please
