avast stops all downloads from web - Asus Game first incompatibility!

Avast Free Antivirus / Premium Security
1

I own avast internet security 2015 license.
updated to ver. 2015.10.2.2214
but also with the previous version gave me the same problem.
windows 8.1 64bit

new computer, with mcafee pre-installed. uninstalled with mcbr properly.
After that I installed avast, but blocks all downloads from google chrome, virus updates (says host unreachable), opening the pages and images internet malfunctioning.
the only way I can make it all work is to disable avast internet security:

  • web scan
  • firewall protection
  • dns protection
    it’s like not to have practically nothing on.
    I tried with another pc, putting avast with the same basic settings, and everything worked properly. I also reset the computer’s operating system on new computer, and also tried uninstalling avast with safe mode and the tool avast.
    did not work anything.
    please help.

“Host Unreachable” will usually suggest that there is a routing issue. The datagram delivered to the network specified in the network ID portion of the IP address may not have been able to get sent to the specific host indicated in the address.

You may want to take a look at this: Destination Host Unreachable - Reasons and Solutions

It can be caused by malware.
I suggest to start with this:
https://forum.avast.com/index.php?topic=53253.0

If nothing comes up, at least a possible cause is ruled out.

as I wrote, it is none of these things (though I had already tried an anti-malware software) but some setting or something related to antivirus, because it caps off in real time, that’s all back to work
anyone have any idea what can be? it is not possible that I should turn off the three guards:
Web
dns
firewall

to run my system normally

5

but the diagnostic logs (FRST) from the guide eddy linked to may help … essexboy may spot the problem :wink:

6

you’re right, here it is.

antimalware
farbar recevery
aswMBR

essexboy should be online in about 2-3 hours :wink:

He is on-line now I have sent him a PM and informed of your topic.

13

Hmm it is pinging google OK

Could you go to control panel > internet options > connections > lan settings
Ensure that it looks just like the screen shot below.
OK out and try again

14

yes, it’s the same.

could be useful if I re- disinstall/install avast?

I tried by safe mode (this is third time) and this previous Avast version seems functioning:

avast 2015.10.0.2208
virus definitions 141107-0
definitions number 2.745.363
I tried a few downloads and all was ok.

now I re-installed the last version:
avast 2015.10.2.2214
virus definitions 150310-1
definitions number 3.648.316

and nothing work -.-
is that possibile?

15

Could you clear all the rules in the Avast firewall and see if that does anything

16

Done.
Ma nothing changed, unfortunately.

17

I wonder if there are still elements of the mcafee firewall there as it is allowing the older version to run

Install the older version while I have a thunk about it

18

I was thinking the same thing.
But I must make a correction to what I said before: unfortunately now using the previous version of avast (I always run a clean install with safe mode, etc.) nothing works, as in the recent version.

Since it is not possible to occur by chance, I think more than anything else that It worked before, because it came to download files already downloaded previously.
so…in the final moment of the download , when it saves on hd, maybe the file was using the temporary memory to save itself properly. is the only plausible explanation.

ultimately avast still does not make me do neither

  • download files
  • navigate anywhere on the Web if there are images or banner pages,
  • update drivers or utilities to download from the internet

perhaps some elements of mcafee are still present.
Should I try to contact mcafee support?

19

As a test temporarily disable webshield, does that have any affect

20

Not.
If I don’t disable all 3 protection (firewall + dns + web) nothing change
