Free BETA VERSION OF AVAST 6

How to get it
Free AV: http://files.avast.com/files/beta/6.0.934/setup_av_free.exe
Pro AV: http://files.avast.com/files/beta/6.0.934/setup_av_pro.exe
IS: http://files.avast.com/files/beta/6.0.934/setup_ais.exe


How to install it
Just run the setup executable (links above). This version needs to be installed from scratch, i.e. updating from a previous version of avast won't work. This will be fixed relatively soon - however, for now, the only option is to really uninstall the version you're using (if any), reboot, and install this beta.

Also, if you have already used a previous beta of the standalone WebRep, it's better to uninstall it before installing avast 6.
