Avast Blocking Access to Internet After Update 18.6.2349

[REDACTED]

We have an idea of what is wrong.
To confirm it, could you please check and post file version of these files:
- "C:\Program Files\AVAST Software\Avast\aswStreamFilter.dll" (or in your Avast install folder)
- "C:\Windows\System32\drivers\aswStm.sys"

Thank you,
Filip

I find it kinda weird that the language in the aswStreamFilter.dll says Czech when the install language is English  Unless this has to do with Avast being a Czech company and nothing with the installation language

Hi citizenkenneth, thank you for your screen. It seems that aswStreamFilter.dll was not updated to new version on your PC and we need to find out why. Can you please export also "HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\aswRvrt\Parameters" reg key and upload it to our FTP server? Thank you

Is anyone having a similar issue with Google Chrome?

Yes, laptop got stuck completely. I followed the advice on malwarebytesforum and turned off the real site protection. It works...for now.

Hello,

We have identified the issue as a problem during program update, that left some old Avast stuff there, that should have been updated.

To fix the problem please perform a repair: https://support.avast.com/en-eu/article/Repair-Antivirus
Or uninstall and newly re-install your Avast Antivirus.

Permanent fix for the update issue is coming in future version.

Thank you,
Filip

some french users with this issue seem to say repair doesn't work  stream filter stays with v.17.8.3705.0

Or uninstall and newly re-install your Avast Antivirus.

this seems to be the solution waiting the next update

Repair Avast:

If Repair doesn't fix the problem, try the following:
Clean Install of Avast:

users do not need this kind of help that has already been given above
A repair doesn't work !!!
there is no need for a clean installation, a simple re-installation works (according to users), as already proposed by Filip Braun.
Of course the clean installation procedure is generally proposed in the French forum in a post-it topic called "toolbox" that I created to help French users (and yes, I spend time helping myself) ,procedure to use only as a last resort, and not at the slightest opportunity.


My intervention was a simple report and not a request for additional help, French users were able to solve their problem with Filip Braun's advice (which I translated) , thanks.

I posted this issue on MWB's forum and then came here. I had this problem after updating Avast on thursday. Currently I have Avast set to not load at startup, so its not on and I have MWB 3's web protection set to off to prevent internet blocking and other window related issues such as the inability to access network diagnosis and event viewer. Another problem I had restarting my PC to finish the update, it hangs, and I have to hit the reset button.

I looked for both files mentioned in this thread and found that along with the updated version the old one is still present.

I have same prob. (with Internet Security, Paid Ver)
No internet access.  Affects almost all software which access the internet.
WorkAround= Disable BOTH WEB and REALSite components.

The REPAIR* did not help

Reluctant to do complete re-install .. because of the work, risks and time-expense involved.
Any easier ideas.?

As said before , a repair doesn't work for this issue.
So you haven't choise to wait for new version or re-install it.
obviously no need to do a clean install so work and time-expense 5 minutes ? less than the time for you to post
risk ? aren't you paranoid

My Dell Inspiron 6400 continues to stall after initialing the opening of one program.  I think version 18.6.2349 is causing damage beyond Google Chrome.

My pc Doc found  that the VPN was blocking me getting onto the web !

Several days have passed since the last substantive replies for this problem.  I have put in all Avast/M'bytes exclusions.  I have uninstalled (clean uninstall) and reinstalled Avast.  These did not work.  I contacted Avast tech support and was strongly urged to spend money for "advanced diagnostics" (shame!).  Are Avast programmers/developers working on this?
