CounterSpy from
Sunbelt Software is consistently rated in the top three with SpySweeper and Spyware Doctor but is less expensive (although barato napud ang spyware doctor karon kay good for 3 PCs na).
Now, because I use a 64 bit Windows OS, I upgraded my CounterSpy to VIPRE antivirus + antispyware since VIPRE will run on a 64 bit system. VIPRE is a new program from Sunbelt Software so it should have the best antispyware capability of ALL antivirus programs. But I don't know how its antivirus compares against other AV's although its supposed to be lighter than NOD32 even.
