i dunno.
I used windows defender since it been release(M$anitspyware)
I dunno i guess if people new how to use M$ products they'd realize how good it
But then again for a novice user it would mean it being complicated. in my line of work.
I've test alot of different spyware programs and Windows Defender seems to be best i've used basically.
i'd fix a machine install spy ware software 2-3months later it be bck to square one, windows defender so far has lasted alot longer.
and no i not M$ lover
i just given my opinion.
If software is bundled with 3rd party stuff then yes i believe it should be blocked. mainly because so many probgrams out there that do have 3rd party stuff that harms the PC. I hate having to fix it
