Don't stay logged on as an administrator
• Why use a standard user account instead of an administrator account?
• When you are using programs that require Internet access, such as:– a web browser – an e-mail program,
• we recommend that you log on as a standard user rather than an administrator.
• That's because many viruses and worms can't be stored and run on your computer unless you're logged on as an administrator.
31
Manage Accounts in Control Panel

Sign in each days as ‘Standard’ account, NOT as ‘Administrator’
User Accounts

– If you are hacked while on the internet:

– you can do almost anything that you can do with an administrator account,
• Windows will ask you to provide a password for an administrator account.
