It really is not necessary these days. Unlike Anti Virus packages that force Windows Defender to be off as only one AV package should/can be operational on a PC, Malwarebytes at least operates alongside Windows Defender or your chosen AV package if you have gone that route. I personally have stopped using it. It is truly unnecessary. It uses PC resources that could be used by your sim. Use it only if you visit high risk sites. Otherwise no, don’t install it.

Usually uninstalling these packages leaves an high count of junk on your PC, files and folders and registry entries. They are difficult to remove cleanly. Best is that when doing a fresh Windows Install in the future, avoid these things like the plague unless you have a very specifc reason for installing, for example you company insists on a particular package for network security harmonisation.

Ok, thanks for the information. 

I dont use 3rd party payware AV. Win10 Defender is just fine & works perfectly. These 3rd party AV are an absolute pain.

Image your drives regularly onto an external HD using the excellent free Macrium Reflect and keep that drive safely disconnected from the PC. Thats it - complete backup security. You can even mount the image in Win Explorer to access individual files. This along with making sure your OS is always updated is all the defence one needs these days without needing to chuck money at 3rd party AV IMO.
