I use WebWasher and ZoneAlarm Pro when I'm online. WebWasher filters banners and ads but ZoneAlarm Pro has the same thing under privacy called Ad Blocking. I am wondering if I could use them both in the same time. I also have AdSubtract PRO which filters ads like WebWasher. PCWorld magazine gives a slight advantage to AdSubtract PRO but WebWasher is more controllable so I use WebWasher .Will using two or three of these ad blocking programs at the same time cause contra effect and is that possible because that programs are acting like a proxy servers. What do you think which is the best ad blocking software? By the way which is the best download manager GetRight, Download Accelerator Plus or Go!zzila?
