You could start by answering this question - Have (or did) you another AV installed in this system, if so what was it and how did you get rid of it ?
This is by far the most common reason for this problem.
Or if no other AV installed now or before, try a clean reinstall:
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 reinstall. 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.
Download the avast! Uninstall Utility,
find it here and save it to your HDD.
- 1. Now uninstall (using add remove programs, if you can't do that start from the next step), reboot.
- 2. run the avast! Uninstall Utility, reboot. If step 1 failed, as it seems to have it may be necessary to run this from safe mode, once complete reboot into normal mode.
- 3. install the latest version, reboot.
