Run-time '481' Error Code on all limited accounts

[GeeTee]

Hello all -

I've just cleaned up a badly infected laptop. It's a shared 'puter w/ 5 accounts, so I changed 4 of the 5 accounts to limited users. Running XP Pro, w/ SP3, everything fully patched. Malwarebytes runs fine under the admin account (showing system as completely clean), but throws a Run-time '481': Invalid picture error code every time one of the non-administrator accounts is logged into. Any advice on what I need to do to get rid of the errors?

Thanks,

G. Thomas
