If you don't have a plan, you may think that your computer is performing tasks when its not, such as reminding you of deadlines or accurately tracking your billable hours. Understanding what you intend for your system and what the computer currently is handling will help you avoid frustration, ensure that tasks are completed, and save you money in the long run. Have anti-virus software. If you are in a high-risk group, you would get a flu shot well before flu season. The vaccine may not prevent you from getting sick, but it may minimize your symptoms or keep you from getting sick as often.
Any computer is basically in a high risk group for getting a virus.
You do not have to be on the Internet to get a virus. Have a computer use policy. Have an e-mail policy. Whether you include it in your computer use policy or put it under separate cover, be clear as to who owns your internal and Internet e-mail, and then communicate that information to your employees. Be aware that you may be compelled to turn over e-mail during discovery or under a court order.
