Spyware and viruses infect an individual or business computer in many ways, from the obvious methods to the sneaky, back door tricks. Viruses are designed to interrupt and alter normal computer functioning and spyware is intended to literally spy on its victims, all the while recording their personal information. Either infection, no matter what the method in which it intruded by, can cause an array of difficulties for the computer user.

Often times viruses and spyware are put into your computer by opening insecure emails and sharing files with infected computers.
