Another problem! Please help...

[systemseven]

When I try to remove a web user it tells me this...

Error: Unable to remove web users: Unable to delete system user big: SysUser->systemRemove() failed: usermng failed: Unable to open process token: (5) Access is denied.

Error: Unable to create SysUser object: SysUser->systemRemove() failed: usermng failed: Unable to open process token: (5) Access is denied.

I use GeneFTP with the latest version of Plesk. What does this mean and how can I fix it?

Thanks.

I had this problem because of Symantec antivirus v.10
It was exactly the same error when I tried to delete domain.
I've stopped Symantec services and was able to delete that domain.
