Avast blocks webbrowser after few minutes

Regarding the clean re-install, I’ve heard that the firewall should be deactivated while installing an anitvirus due to complications in the registry (or something like that). Is this something I should look out for, or can I just install it?

Never had any problems with Comodo.

Check your event log and see if DNS clients events are present, error 1014

system · 2015-03-30T16:26:21.000Z

hm no, there are some '1014’s in it, but no error…

right before the issue occurred today there’s this:

In your “Windows” event logs under system… it will say event ID 1014 DNS Clent Event

system · 2015-04-03T18:21:44.000Z

Hm, so repairing avast didn’t help.

There are few occasions when it says event 1014, but not ever in relation to the internet block :-\

I’m trying the clean reinstall tomorrow I think and will keep you posted.

Pondus · 2015-04-03T18:30:41.000Z

Tried this?
Delete all avast rules in comodo, restart computer, when comodo ask create new rules

system · 2015-04-07T10:34:06.000Z

Okay, clean re-install didn’t help…

Delete all avast rules in comodo, restart computer, when comodo ask create new rules

Going to try this now.

Asyn · 2015-04-07T10:54:44.000Z

OK, report back.

system · 2015-04-08T11:07:36.000Z

Soo, I removed the rule, restarted a few times since then (not purposefully) and Comodo doesnt even ask me to create a new rule…which seems strange, but okay. More annoyingly, it just happened again.

I was wondering, can such a block be caused by visiting certain websites? Or, by opening too many tabs simultaneously?
Because for me it seems like there’s a connection between the block and visiting opening gamestar.de and sport1.de at the very same time. Both sites are very trustworthy (one is a major gaming magazine, the other a major sports channel in Germany), so I don’t think it’s something harmful, but in retrospective the block could be related to me opening those 2 sites simultaneously.

It seems like a stretch to me, but I wouldnt know where else to look for causes

To rule out an infection: Attach your basic logs. (MBAM, FRST and aswMBR…!!)
Instructions: http://forum.avast.com/index.php?topic=53253.0

Here’s the MBAM log, I’m going to edit this posts when I have the others and bump the thread.

MBAM revealed I actually had some malware

aswMBR.exe just stops working when it comes to a specific file located in C:\Windows\assembly\GAC_MSIL\Microsoft.VisualStudio.Tool.Applications

OK, please do so.

system · 2015-04-08T12:00:33.000Z

So, I added the other files, see the attachment post for more details

Asyn · 2015-04-08T12:33:14.000Z

OK, now you’ve to wait a bit…

I see you have CIS installed as well have you tried disabling that ?

CAUTION : This fix is only valid for this specific machine, using it on another may break your computer

Open notepad and copy/paste the text in the quotebox below into it:

Save this as fixlist.txt, in the same location as FRST.exe

https://dl.dropboxusercontent.com/u/73555776/FRSTfix.JPG

Run FRST and press Fix
On completion a log will be generated please post that

system · 2015-04-08T14:24:37.000Z

Yes, I tried disabling CIS, the problem persists. It only gets solved by disabling avast. Of course, there might be an interaction I’m not aware of which causes the problem.

I really appreciate all your help btw I hope we get to the bottom of all this (how very selfish of me).

Have you try to set FF in Comodo FW as a Web browser ? See screenshot
Did you disable Behavioral Blocker in Comodo ? I understand that it interferes with Avast.

Pondus · 2015-04-08T15:05:28.000Z

you could also try to uninstall comodo! … and see what happens then

essexboy · 2015-04-08T16:41:04.000Z

As far as I can see from the logs there is nothing apparent that could cause this

system · 2015-04-08T18:42:27.000Z

Just a heads up, so I don’t keep you waiting. I’m going to wait if it happens again, re-install comodo and report back (in an appropriate amount of time). Thank you so much for trying to resolve the issue!

I set FF as web browser, maybe it helps
