Use Anti-Virus Software
Computer viruses and worms like "Melissa" and "Code Red" receive a lot of media attention because they can spread quickly and wreak havoc on personal computers and corporate networks. You should always use up-to-date anti-virus software that is capable of scanning files and email messages for viruses. This can prevent your files from being corrupted or lost, as well as save you hours of frustration as you try to restore an infected computer system.
Anti-virus software will also protect you from Trojan horses. Trojan horses are typically sent to computer systems through email. They are particularly dangerous because they have the potential to allow others to gain control of your computer system remotely, without your knowledge or consent. These programs can capture and send sensitive information stored on your hard drive to any other person who has gained remote access to your computer.
A variety of anti-virus software packages are available on the market today. Many of these products install anti-virus updates to your computer automatically, as long as you have the update feature enabled.
