yes.

Click on My Aim > Edit Perferences >

In the new window click on Sign On/Off (menu on left side)

Under Sign On you will see a check box for Start AIM when Windows Starts. Make sure there is NO check mark next to that option.

Click Apply > Click Ok.

Next.

On your desktop...

Click Start> Click Run >
Where it says Open: type > msconfig > Press Enter

In the new screen which pops up click on the Start Up Tab
In here you will see a list with check boxes, find the one for AOL Instant messanger. IF it is there (might not be) remove the check mark.
Click Apply > Click Ok > Click Exit Without Restart


When you restart your computer next time, hopefully it should not start up AIM.
