My windows is 7, and I had Avast! 7.0 running, but it’s not running anymore. When I click on this link http://files.avast.com/iavs5x/avast_premier_antivirus_setup.exe (given in my inbox from Avast), it doesn’t redirect to the download, adn when I go to Home i the site of Avast and click on “Download”, anything happens. Help me, please.
