ANTISPYWARE RESIDENT PROTECTION???

Hi! Happy 2008!!! We all know it is not recommended to have two antivirus resident protection. What about “antispyware” resident protection. I have Spyware Terminator resident protection with HIPS ON and recently downloaded the free offer for SPY SWEEPER:this antispyware also offers “antispyware” resident protection so I’m covered two times as an extra layer or am I only conflicting the two resident protections. If so, which resident protection should I keep ON. Thanks!!! ;D

Well, a lot of resources will be used.
I think Spy Sweeper has a better detection rate than Spyware Terminator.
