Thank you Darth.Mikey for posting this.
These days all big companies are working on make all their products faster and faster even if millisecond… and impact of SpywareBlaster is worse than what has been said by them. You can Test it yourself. (Some people will not see difference because don’t want to see)
I would rather trust my AntiVirus and it’s WebGuard for this propose, if I need more protection I will use somewhat which don’t affect performance like HostsMan MVPS and built-in features of browser.
