New version of Avast is blocking all my websites

Hello.

A week ago after updating to the latest version of Avast Professional we noticed that all of a sudden all our web sites are blocked.
No matter if we access them with https or http the all are blocked sayng the contain Url:Mal (no further details).

An examples are those two sites:

www.softsolutions.it
www.nexrates.com

As seen in other posts of this forum I checked them with:

http://zulu.zscaler.com
https://www.virustotal.com
http://www.urlvoid.com/

All those sites says the sites are clean and safe.

I do not understand why AVST is blocking them when other AVs are just fine with them. We are using AVAST for a long time and this issue just came out recently as I said.

I also raised a support request but I was told to contact the virus team (which I did) but no answer so far.
The problem is even worst because one of our customers uses AVAST and they cannot access out sites as well.

Any idea on how to fix this?

I just visited the nexrates.com site and no alerts.

Visiting the hXXp://www.softsolutions.it/ resulted in immediate alert see attached image. URL:MAL is normally an indication that your domain or IP address is blocked. Please modify your domain links to break them and avoid accidental exposure.

I would look for URL links (possibly to 3rd party sites) within the site.

URL:Mal = IP/Domain is blacklisted

The fix for it is out for over 4(!) years.

softsolutions.it has been unblocked, as no malicious activity has been spotted recently. Do listen to what others say, though, as if there is anything suspicious, it might be blocked again.
