I recommend that you post a HijackThis! log in the Hijack portion of Bleeping Computer to rid yourself of some problems. Deadaim is a program to stop popups in AOL Instant Messenger. However, if you didn't download it, you may have a worm that uses the same name. Also, AUNPS2.Dll is malware. It is part of the AlwaysUpdatedNews.com parasite.
My own personal choices for protection are Zone Alarm firewall, AVG antivirus, Ad-Aware, Spybot Search & Destroy, Spyware Blaster and Microsoft Antispyware.
