Why can we not just "get rid" of the malware problem?

Malware are the defects that occur in the operating system due to the virus induces in the system, stealing of the data, failure of hardware in working etc. The damaged caused by malware can be reduced by making various attempts like installing antivirus, working in safe mode etc.

Malware cannot be completely abolished because various new virus get introduced over certain period of time which the antivirus software cannot detect, many hackers produce different techniques to hack the system using powerful hacking software and tools even if the system has the security software and virus scan.

These new malware software are not recognized by antivirus or virus scanning software so they are at time not able to detect and abolish the virus. Thus we cannot get rid of the malware problem but certainly protect the system and reduce it.
