Understanding Antivirus Software: Types, Benefits

A computer virus is a program so designed to harm computer files in such a way that they are of no further use. Like a human virus, it replicates itself by modifying other computer programs and entering its own coding. This virus spreads rapidly to other programs and infects other programs too thus crashing the device. These viruses are a great concern for economies since they cause a huge loss to all economies of the world.

Signs That Depict Your Computer Is Affected

Antiviruses work by perform​ing several functions like

Scanning specific files or directories for malicious programs.
