Avast Firewall prevent Canon Scanner working

[system]

I have Avast Internet Security installed and I have just purchased a Canin MG7550 printer which is connected through the network.

When I try to scan from a PC using the Canon utility the scan falls over saying that the network has timed out. I first tried opening all firewall ports on the scan utility but this hasn’t worked, however if I disable the firewall completely then the scanner works perfectly.

I called Avast and got some total numpty who tried to tell me that because I had 69 spam mails in the past month my machine was infected with viruses and then he said I had multiple AV programmes that were causing the issue - he didn’t seem to understand that Avast disables the Windows firewall! He hung up immediately when I told him that I design software systems

Anyone any idea what is going on, I hVe opened up all ports in and out for the Canon programmes I can identify but the scanner always fails until I disable the Avast firewall.

Hi w.iain.morrison,

I am really sorry about your bad experience. I will request a review of the call to the agent supervisor and will post the outcome.

Regarding your problem, please be sure that the following settings are active:

• Enable the “Private” mode in Avast → Tools → Firewall
• Click on Settings within the Firewall window and enable the option “Internet Connection Sharing mode”

In case you still cannot use the scanner, please send us a support package as instructed here https://www.avast.com/faq.php?article=AVKB33

OK, was working OK now it isn’t working again - exactly the same as before.

I have tried unchecking, the checking the box you suggested which worked initially and then I have repaired the installation - all to no avail

ANy other suggestions?
