I recently had to rebuild my windows box. On this rebuild, I want to run free software if possible or at least, very cheap software (i.e. one low lifetime license payment). Currently, I have reinstalled avast and BOClean and I will download Comodo again when the new version comes out (I am also behind a router) Before the system failure my old box had: the two apps. from Javacool (I can't remember their names: Spyware blaster and something) and I also ran spybot's real time block list (not the tea timer, though) as well as Microsoft's real-time antispyware application (the one with the castle icon that they upgraded to after the MSAS/Giant version. I had ewido, A2, spybot, adaware to do on-demand scans. These in addition to the avast, BOClean and Comodo mentioned above. Well... I am reinstalling and rebuilding now. I am wondering how much of my old set-up for security that I should restore ? Basically, I want a pretty tight system built around BOClean, avast!, Comodo and router. I am not going to pay for anything but BOCLean unless, I can find a good app. with a cheap lifetime license (which I think that SAS has for a limited time?). 1. What real-time anti-spyware would you recommend? 2. any on-demand antispyware, antitrojan, and A-V that you would recommend in place of or in addition to what I had before? Thanks, B.
