Problem with SSL on eCompanies web

Hi, everybody,
I’ve installed the let’s encrypt protocol in my web and I want to configure it together with cloudflare but I am not able to and since I have activated it… Avast detects the web as a virus :S

My web is this http://ucompanies.co.uk/

Can someone tell me how I can fix this problem and why the antivirus is doing that?

Thanks!

First, break the link to a suspect site hXXp://ucompanies.co.uk/ to avoid accidental exposure.

Second I don’t get an alert by Avast when I checked the site.
So being a trusting sort I wonder is this isn’t site promotion, I told you I was a trusting sort NOT.

What is the detection is supposedly giving (please post a screenshot of the Avast alert window) ?
