Hi again blodflekk,
I was already told you my opinion and experience with AV:
Kaspersky is much, much better than any AV in your mention. If you really want to change them then try with McAfee or even Norton. That's three TOP World AV any other is in second leauge (for me).
For FW i agree with you ZonaAlarm is No.1 but Comodo is also very good, maybe you just need to wait some time until ZA start with some version for 64bit.
I hope that other SCF Visitors will also reply to this Thread with their opinions and experiences !?
Regards,
S.
