Drop ZA and try again.

First, be sure to get rid of all remnants of your prior installed AV(s).

Then:

  1. Download avast! Free Antivirus: http://files.avast.com/iavs9x/avast_free_antivirus_setup.exe
  2. Follow instructions: http://www.avast.com/uninstall-utility (Run this tool for all prior installed avast! versions…!!)
  3. Reinstall avast! with the downloaded installer from point 1.
  4. Reboot.

Ill retry, dont know what diff zone alarm firewall ( only ) will do, but give it a go, did use avast clear and ran ccleaner to remove reg entries from previous versions of avast, downloading from your link now and report back in 30min

Add the two lines in your WebShield.ini

UseStreamFilter=0

Reboot afterwards.
