I just bought avast! Internet Security yesterday, downloaded it, and tried to install it in 64-bit Windows 7 Professional.
First, I uninstalled Microsoft Security Essentials.
I then ran the .exe file and it asked me for the license file which I then provided. It seemed to install.
I then tried to run it and it put up a window with some options, one of which would be to scan. It said the program was not running, so I clicked to start it. Nothing seemed to happen. I could not make it do anything, so I closed the window. I tried again with similar results.
So I then tried to uninstall Avast and that did not work either.
I tried to run Firefox to get help, and it did not start, though it tried to.
So I shutdown Windows 7 and restarted it. When it got to my logging in, it asked for my password, but I could not type into that field. I gave up and tried to shut down Windows, but it would not shut down. So I powered the machine off and on and it complained as it came up that I shut it down incorrectly. I told it to try again and I still could not enter my password.
Fortunately, I do full backups, so I restored the whole thing and then it Windows 7 worked again, but that took almost an hour.
Any suggestions? If I just install it again, I would like it to work and not have to restore the whole thing again.
I suggest an installation from scratch:
- Download the latest version of avast! Uninstall Utility and save it.
- Download the latest avast! version and save it.
- (Optional) If you want, save your avast! settings for later restoration (Settings > Maintenance > Back up).
- Uninstall avast! from Control Panel (if possible) and reboot.
- Run the avast! Uninstall Utility saved on 1 in and follow the instructions. Reboot in Normal mode after that.
- Install avast! using the setup saved on 2. Register your free copy or add the license key for the paid versions. Boot.
- Check and post the results.
Please, be patient, boot when it’s said to boot…
