Title: Windows 10 Avast incompatibility
Post by: jafstraycat on October 02, 2014, 07:26:30 PM
So I installed Windows 10 Technical Preview yesterday and I'm really enjoying it so far, but I came to my first major hurdle when trying to install Avast. It won't install due to an incompatibility.  :(

I've tried installing it in compatibility mode with no success.

Is there a beta available I could download and test? I would be very appreciative of any support.

I'm sure there will be further input, but I doubt any peripheral security software developers will be spending much time with W10 at this point.
 I don't know how you would keep up with the constant Code injection\modification by MS to the W10 core while developing further.

5 minutes after a preview version is released and you expect AV to be compatible    ::)    it is now that work may begin

avast will work when the OS is ready to be released

Forgive my insolence, but EVERYTHING else I've installed has been compatible with the single exception of antivirus. But, considering MSE was also incompatible, I'm sure this will be the norm for now.

I would hope that Avast will eventually put out a beta I can test with W10. Fingers crossed! :)

The same thing happened with win8 technical preview - MS blocked anti-virus applications other than those approved ones - at technical preview launch that was only windows defender (which was part of the OS installation).

So I don't see this being any different for some time.

Avast had early program updates for win8, but was still blocked by MS.

Follow up:

Both Avira and AVG were compatible for installation.

While I DEFINITELY prefer Avast, I need SOME sort of protection for now... so, Avira it is (for now).

I find this interesting and would like further info, I Quickly looked on both Avira and AVG forums but didn't spot anything,
Let us know how this works out over time.
If you know of others posted in forums that have achieved successful install and consistent operation of these AV's I'd be interested in a link. :)

Be wary. Just because an anti-virus does not fail to launch when installed on Windows 10 does not mean it will provide you with the same level of protection it would under Windows 8... though some protection is obviously better than none. The same sort of relationship exists with all other software and drivers that you might use on Windows 10.

As a rule, until Windows 10 is listed as officially supported by a given application be very wary of potential problems... and, in the case of security software, of developing a false sense of security.

Edit: and if they claim to have full support for Windows 10 before Windows 10 is officially released be even more wary (suspicious even). Because Windows 10 itself will be constantly changing until it is released claiming full support for it before that time would be quite foolish on the part of the developers.

Avast will also cause issues with connectivity. DO NOT UNINSTALL ANY OTHER NETWORK ADAPTORS if you have any i.e Tungle, VPN as you will be in a world of poo. Avast blocks Gateway settings etc and you can not flush it you will no have NET regardless. the only way to fix this on windows 10 is to do the repair in recovery option in pc settings. uninstall all apps e.t.c. tried for hours upon hours. (Limited Connectivity / No Default Gateway ). Comon problem updating from windows 7 - 8 and also windows 8 - 8.1

UNINSTALL AVAST before you UPDATE to windows 10. also run the removal tool. I will wait for avast to have some compatibility as it is well worth the wait and I will just stay away from fishy sites and torrents.

Fixing what? It's almost impossible to get any third party software to work on
something that isn't even developed enough to be reliable. You need to be reasonable
enough to know that MS could make code changes which would make any third party
software unusable. At least wait until Win10 is in beta stage.

As far as Avira and AVG go, I wonder about their effectiveness on an unstable platform.  ???

The replies of some above imply they are just upgrading their main Windows setup with the Win 10 TP.

My God, people, what are you thinking?

This is not a new release of Windows.  It's a Technology Preview.  It's not stable.  It's not trustworthy.  It's not even beta software.  It's just a development build.  And it's going to expire.

You want to test Win 10, great, more power to you - but treat the system you test it on as A COMPLETE THROWAWAY.

I would suggest testing it on a virtual machine or at most a physical computer that you had laying around and that had absolutely no use before - certainly not as an upgrade to your working system!

You DO know it's going to expire on April 15, 2015, and almost certainly not be upgradeable to the actual release, right?  Many people were surprised that Windows preview versions expired (and they lost their programs and data) last time with the Win 8 previews.

Upgrading is ridiculous. I totally agree with you NoelC (Amazing). It is however not the totally the unstable OS you make it out to be.
Some of us have been beta testing Windows 9 for quite a while and Windows 10 is still Windows 9 renamed.
It's been around for some time.
Do not however upgrade your current OS to what is still not a finished product and, may need to be replaced when the final version is released.
Run it on a separate partition on your hard drive or on a virtual machine.

Think what you want but base code in Windows 10 is Windows 8.1 with some adds. So thats why most of the programs work. I got all my 40 programs running on Windows 10 but not Avast, just saying.

I installed Windows over a Clone of Windows 8, with all programs intact. Avast was working properly until October 5 .

Then on booting windows 10 received this screen say.
"
Windows Defender is helping to protest your PC
The following Malware protection software couldn't be turned on:

avast Antivirus

Windows Defender was turned on Automatically to help protect your PC. To use a different security
software, you can browse Windows Store or contact a security provider listed to get an up-
to-date version.

It was at this point that Avast stopped working. An was automatically deleted from my computer.
As i watch until the Orange Avast logo's animation before starting my daily Windows 10 updates and tests.

Why would you even try MSE when Defender is included in Win 10 and IS MSE?

Defender in Windows 8 and now Windows 10 is a combination of MSE and Defender wrapped in one package.

He refers to the Windows 10 Technical Preview, which was released since October 1, but Avast doesn't work on Windows 10 for now. The conclusion of this is that we have to wait for an announcement or something that they tell that Windows 10 works on Avast, because it doesn't work by now.

While I won't agree that Tech preview is unstable I will say I have tested a few anti virus programs including the newest Avast 2015 without install issues but every antivirus besides the built in Defender has been getting false positives from main windows components even in a fresh install environment for right now I would suggest keeping to defender or praying that your faster than your AV quarantine routine and can keep it from removing a component like say the LoginUI that once stopped and quarantined will force the system to reboot and keep you from logging in without restoring to a system restore point :)

Well I wasn't fast enough to stop newly installed Avast 2015 from marking several Win10 system files as root kit components... I however I did stop most of them by selecting "do nothing".  Now I have no keyboard driver. I can boot and mouse around just fine... cant type a password, or even hit ESC during boot... not sure what that's all about.... back to tinkering....

Not even on the latest build Windows 10 build 9860.

Maybe all the problems you're having with Windows 10 are a reason why you were able to install avast.
It isn't possible on a regular installation of Windows 10 to install the current version of Avast.

If it won't even install on some Win 10 systems, is it any surprise that on others where people have managed to squeak through the install there might be run-time problems?

Win 8.1.2 10 runs okay with the Microsoft-provided antimalware solution for now.

Well like many others stated Avast isn't yet ready for Win10 also the Technical Preview isn't what Windows 10 will be in the end, for now it's more under the hood testing than actual radical changes in UI or features, but they will slowly release by updates some consumer features, but not all i think as they got to hold something for the announcement day.

I doubt it. I think the last preview build will be a release candidate and there will be very few, if any, changes between it and the final release.

I was talking about Technical Preview, it's not like i work for MS and know for sure, but these are Belfiore's words, also a RC is too far from now to talk about it, but you are right, between RC and RTM there might be little to no changes

I need to add that after the update to build 9860 just now (forced reboot) avast managed to auto delete WWAHOST.EXE EXPLORER.EXE and BackgroundTransfer.exe without quarantaining or asking what to do... It just deleted them on the spot making any kind of "usage" of the OS impossible.

Been running Avast and W10 for quite some time now but this was something I didn't suspect at all... Maybe look for false positives or a "version warning" before hitting the OMG it changed, - I am going to delete you now - solution...

Angelique, I STRONGLY suggest you use the AvastClean tool and fully remove Avast from your Windows 10 system.

For almost everyone it just fails to even start the installer.  Somehow apparently it installed for you, but you can't hope that it will work properly.  With antivirus software if it's not advertised to be 100% compatible with a particular operating system, it's simply NOT COMPATIBLE.

The problem I have (had) with it, it deleted critical files ie. MAIL does not open any more. Windows defender will not work any more.  Basically anything dealing with metro was considered a threat and was deleted via Avast... ow have to do a warm re-install to make Windows 10 functional again

Sounds more like a botched Windows 10 or a third party Windows 10.
That may also have been why you were able to install Avast.
Avast does not install on Windows 10 unless you either modified Windows 10 or Avast.

Yes it is. I may just have been lucky, but I installed it without any problem on Windows 10 build 9860 - I ran the initial scan but haven't have time for the boot-time scan yet. The only problem to show up so far is a false positive popping up every now and then reporting C:\windows\system32\rundll32.exe as Infection FileRep Malware. Luckily, it didn't remove it to the bin.

Well I managed to install Avast 2015 on Windows 10 build 9879.
https://forum.avast.com/index.php?topic=93544.msg1151014#msg1151014 (https://forum.avast.com/index.php?topic=93544.msg1151014#msg1151014)


I then proceeded to go to msconfig and restore the boot order to Windows 8.1 as primary.
Once I rebooted, I received a little message to the effect that No OS was available.
I used a USB repair drive to repair the problem and was given the message that the Hard drive couldn't be found.
I removed the HD from the system and attempted to read the HD on another laptop just to see what's going on.
The HD was totally dead.... No reviving... No mouth to mouth... The drive simply had a massive heart attack and died.
Now isn't that nice... Here I am in the middle of a tour in Florida with another 5 presentations to go and one DEAD Computer.
The good news is that I'm spending the weekend with relatives here in FL and picked up a new HD from the store yesterday.
It's been a long night but Windows 8.1 is back in business and the presentations are back on the desktop.
I might for right now only be using Office 2010 instead of 2013 but, the presentations don't care and I don't either.
My Image backup is safe at home on it's external HD. I also have a brand new computer waiting at home that arrived
the day after I left.
I actually think this old computer knew about the new one at home and wanted to teach me a lesson.
I don't know if I'll be re-installing Windows 10 build 9879 at this time. I think I'll wait till I get home to do that.
I might also wait with installing avast on the Windows 10 partition till Avast is really ready to support Windows 10.
Lesson learned. I might have been thoroughly tested but, I think it was a lesson well learned.
There's a time and a place for everything.

Does that include Windows\System32\Control.exe
Avast notified me that it was infected and removed it even though it should have gone to the chest.
I managed to retrieve the file from another computer.
It hasn't been discovered on the other system which was updated to Windows 10 yesterday.

Addendum: As it turns out, Avast Internet Security wrongly considers msiexec.exe from Microsoft as malware and blocked me from installing software. It did not put it in the virus chest but consistently blocked any program that relies upon msiexec.exe to install, from actually installing. I was able to install programs if I disabled all shields until restart.

As it turns out, it also messes with Intuit Quicken Deluxe 2015, which it allows to install, but after installed and accessed my data file, upon subsequent openings of Quicken; revert to "Open a file/import a file/start new"

Even though Avast 2015 can be installed on Windows 10 by using the online installer,
doesn't mean that Avast is ready to run on that Preview Release version of Windows 10.
I needed to take the Control.exe file from a windows 8.1 system and add it to Windows 10
in order for Avast not to delete the Control Panel from the Windows 10 system.
When you play with early pre-release software you can expect all kinds of unexpected glitches.

Hi Bob,

Could you please list all the kinds of unexpected glitches that you expect?  Thanks.  :)

Just funnin'.  Happy holidays!

In all seriousness, an Avast dude has said somewhere around here that this version may install, but you'll need to wait until some future version (possibly the next) before it's considered compatible (he used words something like "works smoothly").

I don't expect any just need to deal with them as they show up and always have a recent image backup handy.
Happy Holiday to you as well. :)

Solved!  Found the solution on YouTube. 
https://www.youtube.com/watch?v=7Q4f9ezQ2j8

Download the online installer from Download.com
http://download.cnet.com/Avast-Free-Antivirus-2014/3000-2239_4-10019223.html?part=dl-85737&subj=dl&tag=button

When installing use "custom setting".
Uncheck "Grime Fighter"  not compatible with Windows 10.
I also unchecked "Install Chrome".

After doing this Avast 2015 is working on my Windows 10 64bit just great.

Right click start menu to bring Command Prompt (Admin) enter Bcdedit /set {bootmgr} displaybootmenu yes, then restart press F8 upon Win boot to enter Safe Mode, choose Safe Mode with Networking. Insert a USB stick that contains Avast Pro version 8.0.1489300, and current license file. Force install old Avast version in Safe Mode  and reboot computer. Press F8 during Win boot choosing same Safe Mode option previously mentioned. Open the Avast program which will offer update to new version, choose custom install and insert license file.  Restart the computer and boot normally check for updates and scan with new Avast. To turn off text boot mgr in Command Prompt (Admin) use Bcdedit /set {bootmgr} displaybootmenu no. Problem Solved! :) Will not work for build 9926 worked in previous build!

Avast has been working fine for windows 10 preview until they last Sunday upgraded to version 9926, all version before that Avast has no problem with Windows 10 preview. We has been running Avast both with Windows 8, 8.1 without any problem and also Windows 10 until last update.

Thanks but I'll wait for Avast to make things a bit easier. Especially for the average computer user. :)

I Upgraded from windows 8.1 with Avast working to Windows 10 build 9879 and avast was working. Continuing to work until I upgraded to Build 9926 on January 21 2015. Was not watching as to exactly when it quit but functioned before installing(was running Avast 2015 at that time). Was too busy playing with Cortana to notice. It was only when I was looking how to write script files for Cortana that i noticed avast 2015 was disabled but still installed. So I tried to reinstall but all attempts failed.

There is a video showing someone installing avast 2015 on Build 9879, Search web "Avast 2015 on Windows 10 build 9879 ".

Also most of my previously installed programs unregistered at the same time, so I was extremely busy re registering them.

The current version of Avast is not compatible with the latest release of Windows 10. I had no problems on the previous build of Windows 10 and hence, was able to
produce the video.
Patience, I'm sure Avast will release a version that will eventually run on Windows 10.

I can confirm that Avast it's not even installing in Windows 10.

I'm getting:

"This program has compatibility issues" and won't let me install it. I tried to change compatibility with Windows 8 and Windows 7 but it's still won't let me install it.
Title: Re: Windows 10 Avast incompatibility
Post by: Koman on February 11, 2015, 04:39:58 AM
First i'll start off with windows 10 is in preview, Microsoft indicates tat you should not be using it on a production system for these very reasons.

"Remember, trying out an early build like this can be risky. That's why we recommend that you don't install the preview on your primary home or business PC. Unexpected PC crashes could damage or even delete your files, so you should back up everything."

Second, anyone who is used to testing for microsoft knows that is incompatible with antimalware programs and usualy printer dirvers until tose vendors update ther software. They typically release their beta around the same time Microsoft does; but i have yet to see one for avast for windows 10.

Third, and finally the good news! Someone mentioned "Microsoft Security Essentials", In windows 8 and newer the virus engine for MSSE was integrated into windows defender. There is no need to install anything, your already protected. MD defender is the only antimalwere that works with these early builds of windows and should be sufficient enough given you're installing any and all security updates.

Sorry for the bumb, but just wanted to add:

It was a clean install directly retrieved from the Windows Tech site. I am running the Entreprise version, not the "normal". As it happens, Avast has been running smoothly ever since I "kindly" requested not to look at the false-positives. I didn't need to do any hacking or what so ever. On the entreprise version, it simply runs out of the box. The only bump I've had was the April update-release where I needed to reinstall Avast, but other than that (and the fact the reporting system seems to not work with the new firewall rules) it runs just fine.

This latest build of AIS may work in Windows 10 but in Windows 7 it is far from being ready for prime time. With all of the issues one would think that Avast would have fixed it by now. This is an RC? It is working as if it is an Alpha.

Same thing here. Updated to Windows 10, updated Avast program. No connection via Secureline VPN. Called Avast. The person told me that I purchased VPN for a different operating system, and that I would have to pay $179 for a year of support to fix it! I hope this is not true. Avast will lose a LOT of customers, if so.

Also tried the Registry change which others have discussed. No luck!

Did I waste my money on a dog? I paid for 2 years of VPN!
