Good day,
I am an Avast IS user and purchased and downloaded Forza Horizon 3 on my PC. Starting the game it crashes at the end of one of the intro movies. I had a look around on various forums for fixes, and the predominant solution that fixed it for many users was to uninstall Avast antivirus. I am reluctant to uninstall Avast to test if this works on my system. I tried adding an exclusion for the game folder and running in silent mode, but it made to change.
Any ideas on what might be causing this?
Here is a link form the Forza forums below:

This also happened to me.
Can confirm Uninstalling Avast fixes this issue
-
What OS/SP ?
What exact version of avast ?
Does it make a difference if you disable the shields (do it one at a time) ?
-
Windows 10 Pro 64-bit, Avast Internet Security 12.3.2280. I tried disabling the shield for 10 minutes (6 shields disabled), ran Forza and it still crashes after the first title video. Not really familiar with the number of shields and what they do.
-
I suggest to contact avast and have them take a look at the problem > https://support.avast.com
-
Thanks Eddy, I have submitted a ticket.
-
Reported to Avast.
-
same issue here, have to unistall for it to work, disabling wont fix it
-
kezzaman1986,
please mention you OS/SP version.
It can be the problem is only with a certain OS/SP or even hardware.

Hello,
we are working on resolving the issue, but we are not able to reproduce the issue. Can you, please post your HW configuration, especially graphic card? We observed this with NVIDIA card and update of the driver fixed this.
We also saw that some wokraround with modifiing avast5.ini can help: http://forums.forzamotorsport.net/turn10_postst70863_I-think-I-found-a-fix-for-the-Avast-startup-crash--without-uninstalling-Avast.aspx

In case someone needs it > http://www.cpuid.com/softwares/cpu-z.html
It is a little tool that detects the hardware and has the option to create a report file.

Forza is a broken mess even as it is. Wouldn't be surprised if it's causing random problems by itself...

Hi Milos, thank you very much! I can confirm that this workaround regarding virtualization did fix the problem for me, and that Forza Horizon 3 is running without any issues with Avast activated in the background.
-
Having the same problem, workaround didn't work for me.
Uninstalled avast and now it runs (attached my dxdiag)
Bit annoying when you pay for avast and can't use it :(
thanks
-
Install the latest drivers and see if it makes a difference.

-
Thanks for the reply appreciate it, already installed them last night still the same.
Only thing that's working is uninstalling avast.
Other things I have tried
Reinstalling forza and then resetting the app.
Checking my drivers.
Disable microphones - suggested on the forza forums
Reinstalling avast after a prober clean and uninstall - this causes the issue again
-
Just uninstalled avast, then ran CC cleaner.
Installed it again then followed the workaround
Now its running :)

I've been using the latest version of Avast Internet Security (at least the latest version for Brazilian Portuguese) v 12.3.2280 and I'm also facing the same problem with Forza Horizon 3 in Widows 10 Pro 64bits Anniversary Update.
I have a PC with an i5 4690, 8GB DDR3 RAM and an AMD R9 280x with its latest driver 16.9.2 and the game crashes some seconds after the game is opened.
I tried uninstalling Avast and the game ran normally after that. I insisted reinstalling Avast to check if the problem stopped, with no luck.
At least if I set Avast for Passive Mode and then restart the PC, the game runs normally. It's still very risky to use an AV on passive mode though, so I expect a solution for this.

Hi,
we actually ran extensive tests on Forza day before launch and ran only into crashes that were not caused by Avast but rather by NVIDIA video drivers. Updating them did fix all crashes regardless whether Avast was installed or not. We made especially sure to also enable virtualization as was reported on the official forum that might be the source of them problem but still no luck in getting Forza to crash :)
May I ask you to try to reinstall Avast now that Forza is working and let us know whether it changed anything? Our suspicion is that it was the restart itself that made Forza work, not the actual presence of the antivirus. I see several of you already did that but please let's have it as the first step of our diagnosis for everyone - please try to reinstall with default options (backup your avast5.ini and remove it). Is there anyone who was experiencing crashes and can now play after reinstalling Avast without problem? Do you experience it even on Avast Free? Do you experience it on Avast Free with Passive Mode on?
If this doesn't help, the issue then has to be tied to either specific configuration of Avast, its interaction with other programs or hardware configuration. Anything you can tell us that might be in common between everyone experiencing the issue will be of big help.
-
My steps i took to get it working
First - Installed forza as you would any game - crash
2nd - Updated drivers for nvidia and windows- restart - crash
3rd - Tried the Avast workaround - restart - crash
4th - Uninstall Avast - Restart - Runs
5th - Installed Avast - Restart - crash
6th - Uninstall Avast - Run CCleaner - Restart - Install Avast - Restart - Game runs
So For whatever reason that worked for me.

Yo guys, found a fix on forzas support forum thought id come back and share.
First open Avast and go to Settings > Troubleshooting and turn off the self defense module(this is only temporary).
Set your explorer to show hidden files and then browse to "C:\ProgramData\AVAST Software\Avast" (it will be there even if Avast is not installed on your C drive) and open "avast5.ini" in Notepad (I use Notepad++) as an admin. Under the common section add "VirtualizationMechanisms=0" (without quotes) and save the file.
Restart your PC and re-enable the self defense module and the game should launch without crashing.

Can someone from Avast team comment if this fix is considered safe?

Yes, go for it.

hey guys
I was able to get past this issue by putting AVAST into "Passive Mode" after a reboot I could get past the intro video and play forza no problem.
Once I launched the game I just turned passive mode off and ptu avast back into active mode and no problems thus far forza is working.
I have not tried the "VirtualizationMechanism" fix yet. however if my method fails I will then try that.

Just wanted to confirm that this works and say thanks man! I was playing FH3 on another hard drive with a new copy of Windows 10 with no antivirus because nobody could figure out the issue.
-
Thanks for your input! We were able to finally reproduce the issue in our lab and it indeed seems it has to do something with our virtualization (possibly clashing with Forza's self-defense mechanisms, unconfirmed yet). Will keep you updated once we know more - until then, please use the fix involving settings VirtualizationMechanisms=0 in avast5.ini to disable it.

Hi folks, I'm having trouble finding the avast5.ini file. I've followed the instructions, navigation path and enabled hidden files but there's no avast5.ini in that directory. I'm a bit puzzled, can anyone help please?
-
The location depends on what OS you have and where you have installed avast.
Simply search for it.

I can confirm that I'm also having the same issue.. can't find the avast5.ini file - even with view hidden files turned on, and I have done a search of C:\ for this file.
However putting Avast into "Passive Mode" from settings > troubleshooting and then restarting computer, launching Forza 3 horizon then alt tab and turning passive mode off again is still working as a work around to the problem, I can play forza no worries doing this.
I would like to do the ini fix but can't find it ??? :(
-
Here's the path for avast5.ini: C:\ProgramData\AVAST Software\Avast
DJBone

Ah yes there's my mistake, I was looking in Program Files not Program Data directory, they both have similar paths.
-
All of our user-modifiable files reside under ProgramData\Avast Software while all of our binaries lurk in Program Files\Avast Software. Just so it's easier to remember ;)

Hi Avast team
any progress on a proper fix for this issue? so that we don't have to use the work around ini tweak
cheers

Thanks Milos

any updates on this issue, i couldn't edit that ini file (didn't bother with safe mode) so in passive mode, i guess these issues may become more common with other games.

To edit the ini file you first need to disable Avast self defense:

I played Forza a little earlier and then heard about an update to Avast so I installed it a few minutes ago. Now Forza won't work again.

Can you comment on this Milos?
Also is forza crashing at the intro movie?
also Milos can I now remove the virtualisation fix now from the avast5.ini ??

I have the same problem. I bought Forza Horizon 3 and everything ran so smooth until yesterday. Since yesterday, I am expiriencing startup problems with Forza Horizon 3. It crashes in the "Playground" logo, and it does'nt leave and error code or log. I googled it and it said that it may be caused because of Avast Antivirus. I uninstalled Avast but it did'nt help. I also raed that it helps to disable the mic for the game but it did'nt change a thing. Can you help me with this? I just want to play Forza Horizon... Thank you.
(sorry for bad english)

Did you use the Avast Clear Tool: http://files.avast.com/iavs9x/avastclear.exe to remove Avast ???
