Weebly sites being incorrectly being described as containing malware. I have checked my sites with  https://sitecheck.sucuri.net/results/amazingexercises.weebly.com and no malware was detected. So I believe this is something on weebly itself. Also the main site http://amazingexercises.com which syndicates contents to my weebly site has no malware ( and no malware recorded by Google and Yandex too) .Actually I noticed the message on Yandex several months ago but though little of it but now Google is reporing the same.
