I already have windows defender, nod 32, ZA pro, and spyware blaster. Would process guard free be any better than ZAP's built in program firewall? I don't necessarily compromise my security with torrents and dubious sites, but I would like my security to stand up to such threats. I would rather not use PG because most of the time, I find myself having to address alerts using both ZAP and PG free. I would simply turn off my program firewall, but I'm also not sure if PGF offers the same protection as ZAP, namely, stopping programs from phoning home. In addition to PG free (if it would complement my security), can anyone recommend any other ways to significantly enhance my security?
