can free avast work with windows defender in windows 10

My computer went bonkers and I had to remove Norton antivirus. I used the removal tool several times to do that. I tried to download it again as I have it for 3 computers and it wouldn’t do it. so having used avast over the many years since it first came out…I downloaded the free avast. back in the olden days we used avast with windows defender. for some reason I cant get windows defender up. has it changed since the new windows 10 came out…Microsoft edge is on windows 1 but I use internet explorer as I was having problems with edge…I also have Mozilla firefox on my computer. I don’t want my computer to be open to attack. when I check my computer it says it has windows firewall and everything is a go with just the free avast. that means it kills viruses and other things as well. I would appreciate help in knowing more about this.
one more thing. I had a problem with my cursor the blue circle kept turning never turning off when windows updated itself and then the screen began to jump and the icon on the bottom of the site had a light that kept going on and off and then I couldn’t put an address in my address bar…it took hours of trying different things…I discovered that my laptop has the finger thing…and I haven’t set it up…I don’t want to use that…but in device management it has that in there and it as a exclamation mark on it …I tried to fix it and did and when I did the cursor started all over again…that is how I knew it was the biometric device…so when windows updates automatically…go into device manager and make sure that the biometric device has that exclamation mark…that it is inactivated…otherwise the cursor will go bonkers…anyway please let me know if avast works with windows defender in the new windows 10? thankyou…

No.

Defender will/should be disabled when Avast is installed.

Hi vickiec51,

We also better tell you the reason behind this. It is advised, because Avast AV and Windows Defender or MS Security Essentials are resident anti-virus solutions and one of the first rules to follow is never to put two resident av solutions onto one and the same computer, laptop, notebook, device, peripheral.
It is like having two guarddogs that start to fight among each other to dig up each others definition-bones, false positives and less security or insecurity rather will be the result of this misconception.
What you can do is in stead is install a good trio that can play together, allthough they are resident solutions - Avast, MBAM Premium and CCleaner, a wonderful trio to play in full harmony to better protect. Install Adguard too and you have a quartet that cannot be beaten, well they will give a good fight anyway… ;D
