Can there be two anti-virus and two anti-spyware programs running at the same time?
Only one antivirus program on your computer. Ad-Aware, Spybot, Spy Sweeper and Windows Defender (XP only) can all be installed and used to detect and remove spyware. Spy Sweeper, Windows Defender, and Spybot (if you downloaded and turned on TeaTimer) run in the background and monitor system configuration changes. It has been suggested that you have the system monitoring function turned on in only one of these programs. Ad-Aware and Spybot (without TeaTimer) do not run until you open them and tell them to run.
