Mcafee Buffer Overflow Block

Hi, can anyone relate to this or is there something to do to eliminate this re-occuring 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.

 

Thanks
