Title: just bought avast 5 Internet Security, but cannot install...????
Post by: arrrggg! on March 09, 2010, 06:43:52 AM

So it finishes downloading, then a prompt comes up to uninstall it...no other options just unistall, I click NO or cancel, it says something to the effect of are you sure you want to uninstall?  I once again say NO...long story short I have tried 3-4 times with the same problem, it says the problem may be due to Malware.  What do I do now?

I suggest an installation from the scratch:

1. Download the latest version of avast! Uninstall Utility (http://www.avast.com/eng/avast-uninstall-utility.html) and save it.
2. Download the latest avast! (http://www.avast.com/eng/programs.html) version and save it.
3. Uninstall avast from Control Panel (if possible). If, for any reason, you can't run it, try booting in Safe Mode (http://www.pchell.com/support/safemode.shtml) and doing it from there. Anyway, boot after that.
4. Run the avast! Uninstall Utility saved on 1. If, for any reason, you can't run it, try booting in Safe Mode (http://www.pchell.com/support/safemode.shtml) and doing it from there. Anyway, boot after you've run it.
5. Install avast! using the setup saved on 2. Boot.
6. Register your free copy or add the license key for Pro.
7. Check and post the results.
