If you don't want to disable the task, you can set it to run with the credentials of an administrator account.
Follow MrStatic's instructions (the task was listed under a different name on my machine, YMMV), but instead of 'disable' go to 'Properties'. In the 'General' tab, you'll see in the lower half a section called 'Security options' Left click on 'Change user' and type in the name of an account with admin privileges. Then go to the radio button below and change it to 'Run whether user is logged in or not'. Leave the 'Do not store password' checkbox unchecked... we don't want a password prompt!
Now click 'Ok'. You should now get a prompt for the admin-level account's password. Enter it and click 'Ok' again.
The task will still run, but now other users won't see it any more!
Alternately, if you just want to turn it off for other users, do as above up until the radio button. Set this as 'Run only when user is logged in' and the task will only run for the account you named.
If you feel like experimenting, you could just uncheck the 'Run with highest privileges' checkbox in that same 'General' tab. I haven't been able to determine what AsLoader actually does, and I have no idea if this will cripple the program. But I guarantee you won't see a password prompt!
