Website Blocked By Avast

Avast Business Cloud Management Console & Clients
1

We have a website that is blocked by AVAST. If people visit mclasshome.com they get a connection refused. If I shut off Web Shield on a single PC, they can get through fine. I went to the admin portal and allowed http://.mclasshome.com/ and https://.mclasshome.com/ on the Exclustions. After a reboot and verifying the setting changes, I tested again and it failed. Again I can turn off Web Shield and it works fine.

I also added the same urls for the Script Exclusions (since we don’t know the script), rebooted and tried again, it failed. Again works with Web Shield shut off.

Is there a to Exclude everything from this site since we do not know how it works.

Thank You

There is a vulnerable library used that need to be fixed and there are some problems on that ASN.
Other than that I don’t see anything strange.

What is the message that avast is giving ?

Avast gives no message at all. The browser just states connection refused, but when I turn web scanning off it works.

All browsers give a similar error.

Anything about it in one of the log files ?
Does it work on other systems ?

I looked at the log files I believe it would be in and do not see anything. There are about 3 dozen different files. Maybe I am in the wrong location, do you know where these would be stored?

This is doing it on every pc that has avast. It is a website used all the time and they are starting to use it again now that school is back in session. Has not worked since they been back.

All I know it’s a redirector.

As I don’t see anything strange/suspicious about that website and there is no message when avast blocks it, I suggest to contact avast and have them take a look at the problem.
