A computer virus can hurt a computer in many ways. A virus can disable necessary computer programs and cause it to run slowly, disable the firewall, and may even cause a computer to shut down. There are many ways a computer can catch a virus. Web sites that are unsecured are prime targets. Downloading information from these sites many allow a virus to enter a computer. Another way is through email. Spam blockers can help keep email that might be infected from being opened by placing it in a bulk folder. While some viruses are not dangerous, some can cause serious damage.

Do not open spam. This is the best way to avoid contracting a computer virus. Spam blockers can help a person accomplish this by filtering out unwanted email. A person should delete these messages without opening them. If a person accidentally opens a message that is spam, they should not click on any links. They should simple delete the message. Clicking a link on a spam message could open up hundreds of other messages. Any one of these could be infected.

Run a virus scan at least once a week to make sure the computer does not have any viruses or ad ware. Use spam blockers to keep out all unwanted email. Do not subscribe to online newsletters or web sites unless it is a secure location. Make sure that the web site does not give out email to other vendors. A spam blocker is a wonderful way to help keep a computer virus free. Basic filters are available through most email accounts and more sophisticated spam blockers are available through computer software companies. For those who run home based businesses, this could be a wise investment. Having virus protection software and a firewall program will also keep viruses from invading one's computer.
