I missed the "pro"
I agree 100% Only one
But do use one
on various machines I have Counterspy, Pest Patrol, Spyware Doctor, t-timer, not spysweeper currently,
have not tried SAS, MBAM, or Spyware Terminator for real time
also run Win Patrol on most everything
I do not see a lot of slow down
On my W98 boxes I'm moving over to System Safety Monitor
