There's a few freebies.</p> Personally I use Kerio although ZoneAlarm is very popular also.</p> A google search will find either.</p> If you need Antivirus, antispyware etc too, there's a post in the FAQ's that links to a few options.</p>
Zone Alarm is great www.zonelabs.com</p> </p> If you need antivirus and spyware then AVG does a free version of both at www.grisoft.com</p>
RE: Zone Alarm is great The AVG antispyware is a bum steer.</p> After 30 days all features of any use whatsoever are disabled.</p> If your Windows is a licenced copy use Windows Defender from Microsoft.</p> If not stick to Spybot S&D.</p>
