I'm using Win8 Home Premium, wireless, ZA:

ZoneAlarm Free Antivirus + Firewall version:
Vsmon version:
Driver version:
Antivirus engine version:
Antivirus signature DAT file version: 1118015840
Web Identity Protections version: 1.5.393.22

All traffic are blocked but ZA can update itself, I found I have to set PZ to Med to use internet.

Before this drama ZA killed some malware or the like.

So I did a full scan and after a while ZA said it need "advanced disinfection" recommend close all other apps, I did as told and OS restarted by ZA.

FYI a "desktop.ini" in \system32 (?)was infected need reboot to rectify.

After reload I found the wireless has local connection but no internet access. However I can manually update ZA and other wireless devices work properly with internet.

So I disable ZA firewall and all traffic are back then I enable ZA and set PZ to Med also good.

Please let me know what other settings can help and what further info/log you need, thanks.
