The quality of free antivirus

Hi. I was just wondering about what is up with Microsoft giving free anti virus after 7 was released. I have used it now for a while and it seems to work fine but is it a scam or what? Just asking because it seems weird for them to give out free stuff and there has been allot of controversy linked to ms lately

I just think its M$ using their monopoly tactics and I wont complain about it since its free and it works pretty good.

AV should have always been free in the first place.

Windows Defender is the best. It's free, it's made by Microsoft and doesn't bog your computer down.

Avast is an excellent program. They offer both a free and paid version.

I for myself use Microsoft Security Essentials : I'm fine with it^^

I use Avast. It's worked fine for me thus far (around three years).

I use AVG and have few complaints. It's easy to tell when it's running scans as it slows the computer down, so I schedule scans for when I'm not using the computer.

I think MS Security Essentials is free because they make you verify your windows before you can use it.
Or are you talking about another MS antivirus program?

I just use MS security essentials and panda cloud when I'm on windows

I used to have problems with viruses, then I got the paid version of AVG, I haven't had any issues since.
