Our site (http://gapps.com.br) is constantly being locked for users who have windows with installed avast. 
I have done a scan with the antivirus program, and used several websites like Virus Total, Anaconda, Better WP Security etc … But I have not found problems.
What can I do to prevent this message from appearing? Thank you!
