cookies won't go away

I have 3 cookies that I cannot delete from the computer. They are abetterinternet, z1.adserver, and 2o7. I have run adware removal and it gets them, but they come back at start up. Is there a way to get these off for good? Is it possable they are in the registry?

Restart in safe mode  (just after the bootup screen and before windows starts, press F8)  and run adaware again.  That may get them, but it is more likely that you are going to have to run other anti spyware as well.  I find that no single anti-spyware/adware gets everything, but running two or three of them, one after the other usually gets everything.
Some other good ones are Spybot S&D ( ) which is free, and Pest Patrol at:

Best of all though, is Spy Sweeper at:
