just tried to update avast

[LethalBoy]

It seems like a conflict with ZA and Avast.. You can use another firewall like Outpost or the PC Tools Firewall Plus and then check if the problem continues

BTW PC Tools Firewall works great!!

When you say you closed the program settings, I assume that you clicked OK rather than any other button ?

There is most certainly something strange with your set-up as all of the things suggested before 'should' have resolved the problem, yet nothing we suggest has worked, assuming you followed those suggestions to the letter.

You didn't answer this question - What other security applications do you have besides adaware ?

Try rebooting into safe mode, http://www.pchell.com/support/safemode.shtml, start avast and try disabling self-defence from there.

@ LethalBoy
A conflict with ZA wouldn't have this impact, e.g. not allowing disabling self-defence, though I have little confidence on ZA free (or pro for that matter).

LethalBoy, thank you, I'll try it

sure

Only Superantuspyware for now

Just did it. The self-defence module is now disabled but problem still is.

Problem seems to be in ZA, doesn't it?

[DavidR]

It would appear to be so, you could try temporarily disabling it do a manual avast update and see if that gets through and re-enable ZA.

However, even disabled there are likely to be drivers still loaded that might get in the way. Unfortunately I'm none to familiar with the inner workings of a firewall. So the suggestion to try the PC Tools firewall might be worth a shot, you would obviously have to download the new firewall, disconnect from the internet, uninstall ZA before installing the other firewall and reboot.

Disabling ZA gives nothing. I had to uninstall it completely, after this Avast works perfect. And then I installed PCTools firewall. Avast still works ok. So, problem was in conflict ZA with Avast 4.8, I think

Thanks for the feedback, glad that things are working now.

thank you for your help
