avast disables my network card

I put avast home free edition on 4 new computers with intel motherboards and intel integrated nics.
It seems to be disabling the nic were we can not get on the internet ??? I can uninstall avast and the pc works fine.
Does anyone know what is causing this? I always put avast free on a pc and tell the customer to update to pro, but this is the
first problem I have ever had with Avast.

Thanks First Choice

avast doesn’t disable or block, it scans and alerts to infection, which I presume isn’t happening or you would have said ?

So if there appears to be disablement or blocking there is something else going on.

What firewall is also installed ?
Does it allow ashWebSv.exe internet access ?

  • If it does delete the entry for it and reconnect to the internet, this should force the firewall to ask permission again.

Have (or did) they had another Anti-Virus installed in this system (e.g. pre-installed crapware), if so what was it and how did you get rid of it ?

Okay let’s try this again, These 4 machines I installed this on are all brand new Intel Core 2 Duo machines with XP Pro.
All software is brand new and nothing has ever been loaded before as they are NEW. I loaded Windows, Avast Malwarebytes and Office.
That is it, they work for a little while and one by one they can not get on the web. You look at the network card and there is no connectivity where there was before. You can not use the network card for web or pinging across the network or anything. I thought the first time I had a bad Intel integrated nic, so I add a external nic card and we are back up and running. Then the next machine goes down, and the next and so on. So I know I have a different problem. We pull a machine and go through everything, the only common item is everytime the avast icon at bottom right has a red line through it and the network card goes off. So I uninstall Avast and everything works perfectly, so I uninstall Avast on the previous machine I added the external nic to and everything works perfectly.

I do not know how better to explain the problem but it is being caused by Avast. No other AV ever present, No firewall except windows default settings. I have used this software flawlessly for several years now and love it, and have never had an issue with it interferring with anything before. I have these same machines all over town as it is one of 3 models we build regularly. I put avast and malwarebytes on all of them as they are loded with an image using sysprep from Microsoft. I have this exact make of machine running for months with this software with no problems and now all of the sudden these 4 machines all started losing the nic shortly after Avast was loaded and once removed are back to working fine.

So now can someone please give me some intelligent answer or thoughts as to what to check please.

That is the problem the inconsistency of it, it should either work all the time or not at all.

Unfortunately I have zero network experience to be of any practical help.

The Red Circle with a line through the avast icon is an indication that avast ‘isn’t running,’ usually a RPC or AAVM error if you click the avast icon. So if stuff is trying to use the web shield whilst avast is not working that would fail as to scan content it has to be scanned and the main scanning process ashServ.exe appears to be disabled. Why is the question.

I presume that at the time of all these failures the avast icon has had the red circle with link over the icon ?

So I don’t know if it is caused by avast as it would appear avast isn’t running and the most common culprit for the RPC or AAVM error associate with the red circle is (you’ve guessed it) another AV or remnants of one, but you have effectively ruled that out since this is on a clean virgin system and image install…
