My computer sits behind a router (Roadrunner modem > router > computer). The router has wireless security turned on for my wife's laptop, but this desktop in question is hard wired to the router. Is that enough protection? Or should I also use a software firewall? RR provides a free security suite from CA which I installed and it includes a Firewall. Since installing I get tons of problems getting online, and when I do get online, I get tons of 'notifications' whenever a new page loads. The Windows firewall is off. Would I be OK uninstalling the CA firewall and not running any kind of software firewall? I would still have anti-virus, anti-spyware and anti-spam installed and running. Thanks.
