How to Fix a Buffer Overflow Virus
Malware uses numerous ways to exploit a computer. In the case of a buffer overflow virus, the buffer is used to hold data outside of the memory space allocated for the program. This data can then be exploited to overwirte adjacent memory. When this happens, the computer could crash, the program could run improperly, and the system's security could be at risk for having programs executed remotely or being the target of a denial-of-service attack.
