thanks for your post.
according with
http://www.urlvoid.com, weebly.com have some subdomains infected with viruses.
the problem is that they have a huge number of subdomains. in fact they sell website hosting and development tools for anyone using their subdomains. other subdomains are not related with my website. but, if I understool correctly, my website have been acused as infected because of that.
i cannot understand why it does not occurs with ALL weebly subdomains, just with some of them.
it's also hard to belive that my website is really infected, because it was developed online, throught the weebly tool for making sites. there is no FTP access or something like that... and no direct code editing.
i really believe it's a false positive.
that is a big trouble for me, because right now no one user with avast can access our website.
i'll be thankfull for any help.
