Computer Messed up. Hijackthis log inside

I suggest that you do yourself and your friend a favor, Back up the important data on the system to CD or DVD and then format the HD and restore the Operating System and applications.

Tell your friend not to add everything to the computer that is offered for free. If you decide not to format the HD take mrsinster's suggestion and clean EVERYHING out of the startup files and delete all the toolbars and unused programs through Add/Remove programs in Control Panel.

For the love of God, get rid of all of those toolbars. Uninstall them from Add/Remove if possible, and then go into IE-->Tools-->Manage Add-ons and delete everything except what is obviously legitimate.

In MSCONFIG, remove all of the services in the C:\windows folder from starting up. A lowercase "w" is your tip-off.

Determining good services from bad ones can get tricky if you have a lot of software starting at boot. Depending on the severity of the infection(s), you may want/need to do this in Safe Mode.
