Still, quite worrying enough what they did there.  

Which Firewall would you recommend then?


My basic set :

PFsense + IDS/IPS (i.e Snort, Suricata)

Squid proxy + squidguard to filter ads/malware etc.


And on my local windows pc(s) :

Eset Smart Security
Malwarebytes Antimalware
Adblock Plus
Emet

Especially PFsense is worth trying if you like security.
