So can I replace my SpySweeper with SpyBot?
Yes Sir.... . Mozilla Firefox vs Explorer that has a script and ad blocker aka pop up blocker such as the google or yahoo tool bars have is only additional add ons I have vs what I listed above. My zone alarm firewalls are set on high.
You can purchase enhanced versions of these programs yet I haven’t seen the need due the quality and service the free versions provide.
If you run a web site as I think you do that will require a little more security as I don’t run a web site so that may be an issue someone here can address for ya.
Hope it helps !
Stay safe !
FREE is a good thing sometimes IMO.
