Windows Defender Is the Best Windows 10 Antivirus

[Skunk1966]

I lately switched 2 machines running Defender for about 2 years to ESET IS. On my system ESET found the files i had excluded in Defender and on the other 2 PUPs. Not bad considering 1 machine is running Win 8.1 update 1.

A quite underestimated part of the equation is a fortified browser (to avoid drive-by stuff and obvious mining attempts) paired with a generally sceptic user behavior. Things that sound too good are never true ... this is the internet not any magic realm some seem to expect it.

The thing that made me switch was the annoying amount of background scanning Defender performs for any system related action a users starts, delaying the action upto several seconds.

what do you think of the paid version of Zemana ...would it be a waste of time and effort or is it a good program...hard to go by what is written on the internet because very little is not written about this stuff that is not from the software makers themselves or by people that are somehow surreptitiously  beholden to the software makers....
 so i try to ask at sites like this for honest opinions

Zemana is not an Anti-Virus and can only be used as a secundary scanner next to AV
