I used KIS many years ago. then switched to NOD32 v2.5 (that long ago.)
I have tried Kaspersky several times since and although I know it’s the best protection it’s always seemed a little heavy. Not bad but noticeable.
Just tried KAV 18.104.22.1685 (i)
and it’s unbelievable. Lightest AV I think I have ever seen. I was using Windows 10 Pro stock defender settings before.
Well done fantastic product!
