I was too! So I searched the internet and I found this _very_ nice program called CCleaner ( AKA crap cleaner ).
With this program you can erase "start when logged in" programs ( this doesn't erase them from your computer, just erases them from starting up when you log in ) you can also un-install programs with this program, similiar to the windows function.
Download : Download CCleaner 2.18.878 - FileHippo.com
Homepage : CCleaner - Home
If you don't trust filehippo you can browse their site and find another download link. Thanks.
Hope this will help someone, cause I know it helped me.
and, this is me trying to contribute, don't be so hard on me
