Tutorial: Resolving Keychain Issues
If you can't access your keychain, or forget your password If you can't get into your keychain file because you've forgotten your password or the keychain file appears to be corrupt, there are a couple of options.
First, if you've forgotten your password, you can use the 'Keychain First Aid' utility to make the keychain password the same as the login password. This can be accomplished via the following process:
1. Open Keychain Access (located in Applications/Utilities)
2. Go to the 'Keychain Access' menu and select 'Preferences'
3. Click the 'First Aid' tab
4. Make sure the 'Synchronize login keychain password' box is checked
5. Close the Preferences window
6. Go to the 'Keychain Access' menu and select 'Keychain First Aid'
7. Enter your username and password
8. Click the 'Repair' button
The second option is to completely delete your keychain then recreate it. This routine is useful if your keychain appears to be corrupt or otherwise inaccessible. This can be accomplished as follows:
1. Launch Keychain Access (located in Applications/Utilities)
2. Click 'Show Keychains' in the lower-left corner of the window.
3. Select the problematic keychain from the left-hand pane.
4. Navigate to the 'File' menu and select 'Delete Keychain '(name of keychain)'
5. Check all options for deletion and press 'OK'
6. Create a new keychain by going to the 'File' menu, then 'New' and selecting
'New Keychain'
7. You can now make this keychain your default if you desire by selecting it, then
going to the 'File' menu and selecting 'Make '(name of keychain)' Default'
Login as root and perform repair In some cases, problems with keychains can only be resolved when logged in as the root user.

After enabling the root user, and logging in under this account, again open Keychain Access. First attempt repairs using Keychain First Aid, and failing that, delete then recreate the keychain as described above while logged in as root.
Persistently asked for stored passwords If you are persistently asked for passwords in various applications that you have specified should be remembered in a keychain, your 'login' keychain may not be active for one reason or another.
Navigate to ~/Library/Keychains/ (this is the Library folder inside your user's home folder). Find the file named 'login.keychain' and double-click it.
Failing that, select the 'login' keychain within the Keychain Access application and make sure it is the default keychain by going to the 'File' menu and selecting 'Make 'Login' Default'
Turn off Keychain synchronization in applications having problems If specific applications are experiencing issues when accessing password-protected material, the Keychain may be to blame.

You should not give anyone you do not trust control of your computer.
Generally speaking, they would need to know your login password to make any changes or see your passwords in Keychain. But giving someone access to your Mac would allow them to install software that may compromise your system.
So again, you must trust them to allow them control of your Mac.
Mac anti-virus packages generally are bad ports of the Windows versions, which tend to cause more problems then they solve, especially considering there are no Mac viruses in the wild.
