Avast Internet Security 5 Vista startup failure "aswMonFlt"
« on: December 11, 2010, 06:56:45 PM »
Following update to Avast Internet Security 5 the "avast! Antivirus" fails to
start due to "aswMonFlt" service dependency.

Excerpt "eventvwr":

The avast! Antivirus service depends the following service: aswMonFlt. This service might not be installed.

"aswMonFlt" is not visible from "Services" control panel but is list
in the services registry.

All Avast services are running as "Local System".

Any opinions as to root cause and remedy would be most welcome.

Have you tried to repair the installation?

Hello Ruth Pitts: Sometimes a 'clean uninstall and reinstall of your product is required if a 'Repair' of the installation through the 'Add and Remove' option in the Control Panel does not work as suggested by =YLAP=
I'm sure one of the evangelists will walk you through that procedure if necessary.
Thank you. :)

As mentioned earlier, please try the Avast Repair first:
- Go to Control Panel > Add/Remove programs > Avast Antivirus.
- Scroll down and choose Repair function in the pop-up window.
- Reboot.

If this fails to fix your problem, then an uninstall and clean install is required:

1. Save a copy of newest version of Avast (5.0.677) for the version you need and save it to your HDD:
AIS –  http://files.avast.com/iavs5x/setup_ais.exe
2. Download the Avast Uninstall Utility, aswClear5.exe http://www.avast.com/uninstall-utility and save it to your HDD (it has uninstall tools for both 4.0 and 5.0).
3. Disconnect from the Internet at this time.
4. Go to Control Panel and uninstall Avast through Add/Remove Programs if possible and reboot.
5. If Step 4 fails, boot into Safe Mode (hit F8 repeatedly) and run the Avast Uninstall Tool.  Uninstall all previous versions of Avast you had on this machine at this time.
6. Reboot.
7. Install the newest version of Avast and reboot.
8. Get Internet access and add the license key for AIS.
9. Update the Avast definitions.

Please let us know if this fixes your problem.  Thank you.
