ANTI VIRUS WARNING won't go away from my site

Paul, Have a look @ this article (https://support.avg.com/SupportArticleView?q=own+website&urlname=How-to-report-incorrect-AVG-detection-on-your-website&l=en_US).

I have a site that I designed for a client ‘boatbooks.ca’
I tried to log on yesterday and there was a google warning that is was a threat for viruses
I cleared the site
Uploaded the old files – checking them first with avg to make sure they were clean
I sent a ‘verify’ to google
This morning I logged on to find google has removed their warning ( so the site passed and was cleared by google)
I noticed that while the goodle warning was gone
Avg has a virus threat message notice ( and this appears on everyone computer so not a cookie issue )
I go to ‘details’ and it says ‘ trojan/js/ exploitive ‘
I go to ‘more info’ and it take me to your site which says

“This link on boatbooks.ca is safe for browsing
http://boatbooks.ca/
No active threats have been found on boatbooks.ca in the last 30 days.
However, we recommend caution while surfing on boatbooks.ca
……..so google has now cleared it
And avg is saying I and I don’t have a trojen
 
Help me get this message off the site and get the site back up please
 
Thanks you
