I have disabled all my security to download this product to my computer and this still does not help me out at all???
What errors are you getting ?
Have (or did) you another Anti-Virus installed in this system, if so what was it and how did you get rid of it ?
Where are you downloading from ?
Are you using the small download file (about 300KB) which does an on-line installation ?
If so try directly downloading the full off-line installation file:
Download the latest version of avast http://www.avast.com/eng/download-avast-home.html and save it to your HDD, somewhere you can find it again. Use that when you install. Ensure that you scroll down and select the avast direct download link for the English version and not Cnet as that is for an on-line installation (not what you want to do). - Direct download for avast Home, English version, http://files.avast.com/iavs4pro/setupeng.exe.
I presume that you were trying to download the Home version of avast as the above links are for that.
