Avast blocking my mouse drivers?

Hi.
I have a strange problem going on with my Mouse. I have clean install windows 10 Pro (to get rid of all unneeded apps) and with new apps, i have also installed drivers for my mouse. At first drivers were working fine but at some point stop working. I was contacting the company that makes the mouse, searched around web,… tried a million things but nothing seems to work. So where is my problem? At first drivers, icon was gone (strangely), then as i tried to change settings, they wouldn’t apply at all. After contacting official support they recommend me other drivers which make icon appear in system tray and also show up my “OLD” settings, but as soon as i try to apply new changes it will be constantly loading and won’t save them. If i go into safe mode and try changes can be applied but not in normal mode. So few minutes ago i came across video that shows how to fix this problem (for another mouse drivers, but it does same thing). Anyway, main point of the video is to add mouse folder into “Exclusions” section of windows defender, but as i’m using avast defender is turned off and i can’t do that. If i add them to avast it doesn’t apply any changes (even after restart).

Just wondering if avast could be still blocking changes from applying? Or could it be windows defender bugged somehow? Any ideas what i could try.

Thanks for replying.

There is no avast defender.
Windows is using its own ‘legacy’ drivers in safe mode.
On Windows 10,defender is disabled as soon as another av is installed.
It will only be activated again if you set avast to passive mode or remove avast.

Just get yourself a properly working mouse/drivers.

That is W10 Update that do that, have got the same issue my self.
Windows defender have nothing to do whit it. It still runs in the background when you have Avast or any other AV installed.

Since I use “must have drivers for getting my mouse work as it should” from the mouse manufacturer.
It is truly annoying.
But.
You can tell W10 to not update mouse drivers. And you can do the same at other drivers to. If you have drivers that works better then those who comes whit W10.

I know there is no Avast defender, i was talking about bugged windows 10 defender. I also know defender gets disabled when you install another anti-virus. About mouse, drivers are correct and mouse cost 50€. Not the best but also not the worst. Overall something is preventing it from saving changes in normal mode.

I can’t apply changes like DPI, custom buttons, color changing in normal mode. I can apply those changes in safe mode and they will work fine when windows start in normal mode again but can’t change them. Going into safe mode to change something is kinda annoying and all i could find around the web for this problem is windows defender blocking changes from saving (as it apparently checks every change). I had same drivers, same apps and even avast working before, but duo old apps and some problems with windows i have done a clean install, after a month or so it stop working. So overall i was just wondering if avast could be problem (duo all updates).

A 5 dollar mouse is working fine for me.

Have to buy a new one about every 6 months because those ‘skits’ at the bottom are worn down.
Price doesn’t matter.
They all have the same problem.

Great mouse great price

Well I’m using the Logitech-Wireless-Mouse-M560 on this win10 laptop and a Logitech-Wireless Performance MX Mouse on my XP desktop and both are acting strange. I have not updated drivers so no change on that side. Both aren’t saving changes to the custom settings for changing a buttons actions/assignment as they should. Every so often it stops using the assignment I have changed or set and I have to reset it.

I also get issues (if it is working) when refreshing pages/tabs in firefox (using the changed button assignment), whilst it refreshes the tab, then it jumps to the next tab and that isn’t the saved button assignment.

The whole point of these changed key assignments is to save time, when this happens time isn’t saved but lost, a pain in the backside.

Updating drivers it’s always good idea. Drivers on CD or auto installed drivers could be old and buggy so new version could fix those problems. About using it on XP, some drivers are made for newer versions of windows and might not work on XP.

Personally I have never updated drivers unless there is a specific reason. These are two different mice with different versions of the Mouse and Keyboard software.

Nothing has changed on either system other than avast, which pretty much coincide with avast 17.+ updates. I have a third system with yet another Logitech Wireless Mouse, whilst I don’t use this system as much, I’m not experiencing this issue and guess what I don’t have avast 17.x installed on that.

You could add application folder to exclusion area so avast won’t check it, this could be the problem. Or remove avast to test it out. (or even run in safe mode, try mouse on 3rd PC,…) there are many things that you could try. In my case idk something is not right as in safe mode it works but in normal mode it doesn’t even if i disable avast (not sure if i need to uninstall it to test it out). Btw you could also google your problem as i found multiple topics about windows reverting mouse settings,… but none of them fit for my problem.

Sorry but that would clutching at straws and potentially dangerous adding an application folder to exclusions is certainly more of a security issue than the problem. Avast isn’t blocking the drivers no error or alert, just that all of a sudden they aren’t working as expected.

As I said I have a mouse on my (3rd system, also a logitech, M305) win7 netbook also, but I flatly refuse to put the cumbersome and massive avast 17.x.xxxx on a little netbook, it would totally overpower it.

I’m not seeking help just reporting and issue (minor) that may possibly be related to yours.

Something that you could try disabling the Behaviour Shield before changing and saving your mouse settings.

Hi.
Probably if you add folder/app to exclusions it won’t harm your PC as if you’re download something it goes to other folder and avast checks it. But yeah. I solved my problem.

The process that was causing all problems for me is called “Windows host process (Rundll32)” i have two of them running and as soon as i close one i’m able to apply changes. Just posting this if someone else have same problem.

Just installed AVAST VPN. Mouse no longer working. Windows 10. Uninstalled AVAST VPN, mouse still not working. Mouse works on other computer that has never had AVAST VPN. Any fix?

Try re-installing the mouse driver. Remove it, reboot, re-install.
Never heard of a problem with the mouse after installing SecureLine.
