Advise wanted for new anti virus application

I currently run Malwarebytes and windows defender with no problems.
I had to uninstall Norton from another machine due to slowdowns

Hi.
I've been having a few issues with Avast so I decided to remove it and look for another application.

Big mistake,... it's taken several hours to get my PC backup and running, with lots of issue uninstalling and then after a reboot the Avast installer started and reinstalled itself, that and the following uninstall took over an hour and half to complete !

Did you use the dedicated removal tool?

Using the Uninstall Utility for Avast Antivirus | Official Avast Support

@TomT -

Ensure that Avast is completely uninstalled - cleanly.

Windows Defender for your AV and FW.
Malwarebytes Free on-demand to further check (second opinion.)
SuperAntiSpyware Free on-demand to further check (third opinion.)

That should do it on the basic level.

Quite some time ago, I accidentally installed Avast on my system. I left a box checked on another app. update and ended up with the unwanted AV on the system. I ended up prowling the registry and deleting any reference to Avast to rid the system of the app. FWIW I've run Norton 360 (and now with LifeLock) for years. I have never had an issue with Windows updates with Norton running and the performance issues of the past have gone away with updates to Norton. The only performance hit is when a scheduled full system scan runs and even then it only affects loading a program. Once the program loads, it runs pretty much like normal and the Norton scan takes a backseat to the other app. I have the full scan scheduled for one night a week when the system isn't being used. Otherwise the only indication Norton is running a scan or an update is when a results notice pops up.

I would recommend that you remove Super AntiSpyware and Malwarebytes too.

Why?

I have found they MBAM and to a much lesser degree, SAS, to be useful.
IMHO, Don't put all your eggs into one basket.

The "Common Sense" methodology is great for people that have it.

Security must be done in layers.

I would run all scans manually or at off hours, if your system remains on.
