TorBrowser 4.5.1 does not send viruses on https://vms.drweb.com/online/?lng=en > Scan files

Just after pushing Send button an error page appeares:

The connection was reset

The connection to the server was reset while the page was loading.

The site could be temporarily unavailable or too busy. Try again in a few moments.
If you are unable to load any pages, check your computer's network connection.
If your computer or network is protected by a firewall or proxy, make sure that Tor Browser is permitted to access the Web.

On Firefox portable all is okey. http://sourceforge.net/projects/portableapps/files/Mozilla%20Firefox%2C%20Portable%20Ed./
