SSL Errors that may be linked to Avast Anti-Track

Avast AntiTrack
1

Hi,

I have been getting SSL errors while using Firefox for a few days. After investigation, the cause may be on of the following :

  • Agent web’s “HTTPS analysis”

  • AntiTrack Premium update (my version is 2.2.453.514)

To clarify the errors I get are : Secure Connection Failed +

  • SSL_ERROR_RX_MALFORMED_ALERT (This one got me scared as it made me think it could originate from a malware/virus)
  • SSL_ERROR_RX_UNEXPECTED_APPLICATION_DATA
    [li]PPR_END_OF_FILE_ERROR[\li]

These errors occure only on Firefox, that I have reinstalled from scratch (no error when trying Chrome or Edge). They keep coming up.
However, they stop coming up when I disable the ‘HTTPS analysis’ or AntiTrack.

Regards

Edit : Firefox version 92.0 and some 91.X.X before reinstalling it. Avast full scan reveals nothing with highest sensibility

I’ve been dealing with this issue the past week. Unfortunately I ended up disabling Avast AntiTrack. AT inserts a code in the ‘useragent’ at the end of the string which confuses websites’ “sniffers”. At a minimum "Sniffers determine whether you have an up-to-date browser for their site but still let you in. However, most of the time you won’t be able to connect to the site unless you use a User-Agent Switcher which is a Firefox extension.

You’ll get this error: Secure Connection Failed

You can see your user-agent string by going to: https://whatmyuseragent.com/

Here there is no code appended after the browser version:

Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:92.0) Gecko/20100101 Firefox/92.0

If you see a code after ‘Firefox/92.0’ it will disconnect you from most sites. My research leads me to believe that AT is inserting the code.

I have the same problem. Even the Avast support page does not work. This with Firefox 93.0b3

Only way to stop AntiTrack.

I ran into the same problem with Anti-Track and Firefox. I found that I would get some sort of SSL error for web pages roughly half the time. Hitting the “Try Again” button would usually work. The problem wasn’t restricted to top-level pages, often other bits that load from their own URLs would fail so web pages with multiple ads would show error messages where half the ads were supposed to be. I didn’t mind the ads not working but when the CSS stylesheets wouldn’t load it made for some pretty ugly web pages.

For now I have Anti-Track disabled and that has fixed the problem. I’m not sure when, if ever, it will get turned back on.

Hi, same problem here with Firefox.

With Anti-track work fine. I only need to disable ‘HTTPS analysis’ on Avast Premium Security and the issue disappear.

Hi,

Can you clarify if you are getting errors for all the sites on Firefox?
Could you provide us with examples of websites you were accessing and screenshots of the errors, please?

I’m having the same problem with SSL errors. I’ve just bought this program and am very unhappy its not working properly. Looks like Avast has dudded me my money.

Please dont tell me to use the Support app as I try to install as admin, it asks permission then doesnt work, I cant see a process start up for it either. I’ve dled it several times.
