Attacks blocked but sites declared safe

I have a site which has been tested by Norton Safe Web and is safe yet i continue to get notifications that attacks have been blocked.  The attacks are mass injection iframe and tds.  Can anyone explain what is happening here.  Is the site in fact not safe? and if so why does it have OK from Safe Web?

 

Thanking all in advance and hoping someone can help me understand.

Thanks for the PM.

 

Checking the website now.
