Questions about logfile and registry

I'm working through your list, and have a couple of questions regarding the registry and logfile.

I have a line in the HT logfile:
O4 - HKLM\..\Run: [AOLDialer] C:\Program Files\Common Files\AOL\ACS\AOLDial.exe
Then, several lines down is :
O4 - HKCU\..\Run: [AOL Fast Start] "C:\PROGRA~1\AMERIC~1.0A\AOL.EXE" -b
Are these related? Do I need both?

Also, I have a line:
O17 - HKLM\System\CCS\Services\Tcpip\..\{6AAA99DD-6FAD-4F32-9B77-674C946D7A5A}: NameServer = 85.255.115.50,85.255.112.118
How do I find out what that server refers to? The Hijack This! Log auto analyzer at Networktechs.com indicated it as "Bad if you don't know what it is". Should I disable or remove it?

Appreciate the help.

 

Go ahead and complete the tutorial and post your logs without removing anything; one of teh vounteers here at Major Geeks will look at teh logs and let you know if something needs to be removed or deleted.
