I have seen many computers, particularly Microsofts, that have been mutilated by a virus. Many of the viruses caused the computers to run completely slow and it was near impossible to even navigate the pc for fixing. It is important to know basic things about preventing viruses to keep your computer healthy. If someone hacks or phishes your computer you can be at great risk of them stealing valuable information off your computer. Some hackers will set up a virus that if you open it, the virus will monitor every stroke on the keyboard and in turn will give them your passwords. It is a scary thought that if you keep all of your information, from banking statements to social security numbers, on your computer that someone that may have infected your computer could have access to it all. We must remember that computers are a tool and to not relie on them for everything because they may not always be protected.
