I've built a website for a client who uses Mac with AVG. When he tries to open this website AVG web Shield blocks it because it found about 15 javascript files that contain URL:Mal malvare. A half of these files are written by me and they definetely don't have any malvare. Also I scanned this website by several popular online scanners and they found nothing harmful. 

How can I make AVG stop showing this warning?
