[Resolved] Cannot install Avast free version
« on: August 29, 2014, 10:57:10 PM »
Hi, As with most software applications, I try before I buy. I will be using an information I learn here for my next blog post. If you would like credit, or prefer not to be quoted, please message me a note. Thank you.

I am trying to install the Avast free version and it will not run.
I have tried uninstalling and reinstalling. Same results.
The avast! Antivirus service is not running.
It complains it cannot start a dependency.
The dependencies are:
- AswMonFlt  (cannot find any such entry in services)
-- FltMgr (cannot find any such entry in services)
- Remote Procedure Call (RPC) (started)
-- DCOM Server Process Launcher (started)
-- RPC Endpoint Mapper (started)

Please tell me more about FltMgr, where I should be able to find it, why it might not be running, if this is a known problem with the Avast free version. Recommended next steps Thank you.

You need to uninstall MSE per the vendor's instructions PRIOR to installing Avast.  You can't have 2 AV's on the same machine; turning it off won't work either.
Mac 10.9.4 /Safari and Firefox (NoScript/AdBlockPlus/BetterPrivacy/Ghostey)/
Vista Home Prem (same add-on's)/Avast Free/Online Armor Premium Firewall/MBAM Premium)/ Mobile MBAM.

First, be sure to get rid of all remnants of your prior installed AV(s)..!!

Then:
1. Download avast! Free Antivirus: http://files.avast.com/iavs9x/avast_free_antivirus_setup.exe
2. Follow instructions: http://www.avast.com/uninstall-utility (Run this tool for all prior installed avast! versions..!!)
3. Reinstall avast! with the downloaded installer from point 1.
4. Reboot.

Actually, there is no mention of this in any of the screens. I have snapshots of each of them for my article.
MOST AV's don't care if you are running a second, or even third AV. Norton is a notable exception.

This was very helpful.  and I follow all your instructions in your post. Nevertheless I was still having trouble. However, after repeatedly trying to START the service, it did eventually start. Once it did, I had few (but not zero) difficulties.   They are not worth mentioning here.  The point is I got the application installed.

Thanks very much.
Is there way to mark this resolved?

Now to post on other issues. :D
