A computer virus, in simple terms, is a program that includes malicious codes that can propagate itself from one device to another. Once your computer is infected, it will alter how your computer operates and even destroy the files or prevent the operations altogether. Generally, the virus attaches itself to a file, program, or boot sector. When this happens, you will face great trouble. In such instances, it is essential to visit a good cell phone and computer repair near the Katy store to get the required assistance.
