SOLVE CERTIFICATE INVALID TO ENTER IN WEB PAGE

[REDACTED]

Hi to everybody!

I am new in the forum, but I have been viewing it and the fisrt thing I have to say is that you are doing an amazing work. Once said it, I will told you the problem I have:

My PC dates are these:
Windows XP SP3
Avast 10.4.2233

My problem is that when I want to open the url https://www.canva.com the Avast can not permit to me open it and says this: The Web Shield Avast has blocked access to this page because the following certificate is invalid: ssl275600.cloudflaressl.com. The page I want to enter is a normal page, photograph page in this case and I can enter by others PCs.

In order to solve the problem I have tried these two things:
- Make one url exception in Options > Active Protection > Web Shield
- Make one url exception in Options > General settings > Exceptions

But it does not work. I hope you can help me.

Thank you very much and sorry for my spanish english.

Hi.It is opened in Google chrome with avast!.

OK! This is the page I want to open 

I use always Mozilla, and I have not installed Google Chrome, but I thinh in every browser it should open, is it not???

Yes :)You should try with disable HTTPS Scanning option in Webshield.

Worked for me on Firefox.  Didn't have to disable HTTPS in Web Shield

In many case it does

But the error note is from Avast, not from Mozilla. I suppose what I have to solve is something in Avast not in Mozilla.

On the other hand, I do know the page works correctly, even I am using it in other PC, but what I do not know is why it works in my other PC and not on this one.

Opera 12.17
Avast 2015.10.2.2505 (business)

Site opens without a problem.

The problem being this is an avast and XP SP3 issue as HTPS scanning uses a different method to Win7 or later as the API isn't present in XP and another workaround has to be used and this can and does result in these errors.

HTTPS scanning in XP SP3 is far from perfected yet. It still doesn't work with the avast 2016 beta2 11.1.2235.

Another quick thing to check, just to be thorough...

Please check to ensure that your computer's date, and time, and timezone are set correctly. Having any of these items set incorrectly has been known to cause all sorts of issues. If these items are set correctly, please carry on with your troubleshooting efforts.

Users are receiving that my webpage (idealsoftware.com.ar) is infected when it is not.

Can someone please tell me how to let Avast know about this and stop showing the site as infected?

Thanks,

That has an apparent redirect on the page

I have the same problem. I am use XP pro with SP3. I am using firefox

There are two sites I can't access which previously I could.

1. Malwarebytes
2. Satmap

Is there a solution to this problem please. I am not very computer literate so an easy to  response would be appreciated.

Thanks in advance for help

PS just checked and more sites are affected. 2 examples are Google and BBC

[REDACTED]

In these two days I am browsing and with more than that page I have had problems.

The only solution that I have found is to put off the "Analize HTTPS" in the browser options, but I suppose doing it our PCs will be on risk.

Today XPSP3 users are still 15% and I will not ever understand these kind of things.

Hi,
I have same problems as I described here: https://forum.avast.com/index.php?topic=177236.0
Avast blocks wikipedia, cdburnerxp site. It blocks canva.com too.

I hope it will be fixed someday...
