There are Better AV's than defender, but will it make any real world difference ???
malware gets past them all. Often ( seen it )
thats the reality. :-)
So choose something RELIABLE , avoid AVG,AVAST, etc
Some Free AV products are literally no better then the malware they protect against :sell your browsing history, yep will do: use scareware tactics to con users , thats a yes
Take any 'recommendations' with a grain of salt.
Lots of user bias in 'recommendations' .
IT support company I used to work for forced staff to sell only 1 AV product , that product was really bad in every way. It was chosen because of the bosses bias .
MS has a long long history of poor(or inconsistent) performance from its AV products . Defender may be OK now, but in 6 months , 12 months ....... ?
