Avast Free 10.3.2219 HTTPS corruption

Patrick2 · 2015-06-18T17:40:39.000Z

Yes went to open my yahoo mail, signed in fine, but inbox not loading or anything after that. didn’t check before Installing R3 though, so don’t know if it worked fine before R3 or not. Anyways guess will wait and see if Avast issues a fix for this issue, as don’t wanna really have to remove Avast, and reinstall as yet lol, but will if I have to

Works for a bit, then says Page Cannot be displayed, Does same for youtube lately on this system, Windows 8.1 Pro 64bit with Media center
Avast 10.3.2219 R3 Installed
Over top of 2218, willing to do clean install if will fix the issue

Internet Explorer 11 (only browser installed)

Confirmed.
What happened to the https scanning?
Web pages load slow or not at all.
It’s a little better with https disabled.

Hi, is this HTTPS only issue? No problems or slowdowns with HTTP only sites? Problems complety gone when HTTPS scanning is disabled?

Thanks. Lukas.

Problem being in XP there is no entry for HTTPS scanning in the UI to be able to disable it.

@ lukor

I’m also experiencing problems with some HTTPS page layouts (totally screwed up) my uk.yahoo.com portal page.

David,
the missing settings is mapped to:

WebShield.ini

[WebScanner]
HttpsScanning=0

(Web shield restart will be required after changing the WebShield.ini file)

Patrick2 · 2015-06-18T23:04:43.000Z

With Https scanning disabled, i’m not noticing anymore problems with sites here, played 4-5 youtube videos, (yesterday would play 1 or 2, then would eventually goto Page cannot be displayed suddenly), Yahoo mail wouldn’t load properly, (Does with it disabled so far)

Need to the webshield ini portion on XP Machine and see if that one performs better in a few minutes here

Hello Lukas,

I confirmed that disabling HTTPS scanning in WebShield settings solved the problem.
For example, I cannot access this website with HTTPS scanning enabled.
After disabling HTTPS scanning (and restart of WebShield), I can access it.
https://kaken.nii.ac.jp/

I also confirmed the problem with IE11.
IE11 gave me an error message saying enabling TLS 1.0, 1.1, 1.2 are needed to access the website, although they are already enabled.

Hi Lukor,
I added the HttpsScanning=0 line directly below the [WebScanner] section heading, saved it (confirmed Self-Defence module question) I stopped and restarted the web shield. But it is still scanning HTTPS content.

When you say “the missing settings is mapped to:” do you mean that when I add the HttpsScanning=0 line, the setting should also now appear in the avast UI (As I can’t find any sign of it) ?

Hi Lukas

With Firefox and HTTPS scanning on : I have slowdowns, and on the forum even error messages.
No problems with HTTPS scanning off, so there is definitely something wrong.

Same here, I also got the 400 error quite often, a reload usually helps.

Hallo. We have found a problem in the HTTP(s) scanning engine and fix will be included in next beta release.

But, about the flickr problem, I’m not able to reproduce the problem here with current beta. Is enough to enter flickr and browse the site, or I have to do something else. And is the problem generic or related only to one browser, please ?

Thanks for the conformation.
I didn’t post it earlier, because I was not sure the 400 error was Beta related.

Aside from having found the problem with HTTPS scanning - are you also going to fix the UI where XP users don’t have HTTPS scanning options.

Currently I tried a fix from Lukas: https://forum.avast.com/index.php?topic=172470.msg1224686#msg1224686
WebShield.ini

[WebScanner]
HttpsScanning=0

This however doesn’t stop HTTPS scanning in XP, Firefox 38.0.5, nor does it change the user interface.

DavidR, have tried restarting? The ini file setting should absolutely work, the code is the same for all OSs and on other platforms it works. Of course the hidden gui will be fixed.

I have restarted the system a few times and still no stopping https scanning.

I have just had the system completely lock up today whilst browsing uk.yahoo.com which has https and http content. I’m not sure if this is related, but I have uploaded DavidR_manual-crash-dump.7z to the avast ftp. https://forum.avast.com/index.php?topic=172367.msg1224893#msg1224893

RejZoR · 2015-06-21T06:28:43.000Z

So this is what I’ve been experiencing for a while now. Yeah, only HTTPS pages. I’ve turned HTTPS scanning off for now till next beta version is released.

I have the Beta3 with Windows7 64bit and that site opens without problems
