Macs come with a default Administrator Account that you may use for every computer session. Because viruses and trojans are most harmful when entering via an Administrative Account, we recommend that you have a User Account for everyday use. To create a User Account:

1. Go to Apple Menu > System Preferences... In the System Preferences window, under System, click Accounts.
2. In the Accounts window, the Users tab will display current users for your computer. Click New User...
3. Next, enter the Name, Short Name and Password for the new account. Make sure you do NOT select Allow user to administer this computer. Click Save.
   Note: Select Allow user to log in from Windows only if you have enabled and plan to use Windows File Sharing.
4. The new account should appear in the main Accounts window under the Users tab.

Most hacked computers have either a poor password or none at all on the Administrative Account. To create a password for your Administrative Account:

1. Go to Apple Menu > System Preferences... In the System Preferences window, under System, click Accounts.
2. In the Accounts window, the Users tab will display current users for your computer. Select the Administrative Account (usually listed as Admin under Type), then click Edit User...
3. Next, enter the New Password twice, then click Save.
