What is the Difference Between Electrical Surges & Spikes and Viruses?

Electrical surges & spikes and viruses both represent threats to computers, but there are key differences between them. Electrical surges & spikes come from external sources, such as an electrical power surge or lightning strike, while viruses are programs that can spread from computer to computer or enter a computer through other means, such as downloading a malicious file.

Electrical Surges & Spikes

An electrical surge is a sudden increase in electrical current that is greater than the normal amount. A spike is a very short-lived surge. When such a surge or spike enters a computer, it can cause damage to the computer’s components, such as the motherboard or hard drive. To protect a computer from an electrical surge or spike, a surge protector should be used.


A computer virus is a type of malicious software that is designed to replicate itself and spread from computer to computer. Once a virus enters a computer, it can cause damage to the system by corrupting files, stealing data, or destroying programs. To protect a computer from viruses, antivirus software should be installed and regularly updated.


Electrical surges & spikes and viruses are both threats to computers, but they differ in their origins and the types of damage they can cause. In order to protect a computer, it is important to use a surge protector and install and regularly update antivirus software.
