Buffer Overrun Error

A Buffer Overrun is actually a common attack on a computer that is designed by computer hackers. It is one of the most common forms of security risk, and it happens when unchecked external data is treated as trustworthy. These types of attacks are quite common with C and C++ coding that have poor coding practices in place.


Symptoms of Buffer Overrun

When a Buffer Overrun occurs, one of two things will happen. It could be that your application will abort with a core dump, access violation, or segmentation fault error message. That is unfortunately a best case scenario. In the worst case scenario a hacker can exploit weak files and add their own malicious code which can be hard to catch, until you realize your online security has been compromised.


Causes of Buffer Overrun

Malware can be the cause of Buffer Overrun, especially if the hackers have had their way with your computer’s files already. However, another cause may be a registry that has become corrupt due to being unorganized and cluttered. Whatever the cause may be, it is important to root out a Buffer Overrun as soon as it is discovered.


Fixing a Buffer Overrun

Whenever a Buffer Overrun problem occurs the first thing that you should do when attempting to fix it is run a complete anti-malware scan on your computer.




  1. Locate the anti-malware software icon on your desktop or computer tray.
  2. Double-click the icon.
  3. Run a full system anti-malware scan.
  4. Allow scan to compete.
  5. Any malware that is found should be put in quarantine or deleted.

Restart your computer after these actions to ensure all changes take effect.
