^ So is antivirus enough? or should I look for IS software?
I think in this arena, there are no hard and fast rules.
I ended up with Norton IS after much delving and it works for me.
But, it's possible to get freewares for each function: a good free AV, a good free firewall.....and then, run yr MBAM Pro in concert.
I used to use Comodo firewall on my lappy. I remember it being good.
The prices for top rated suites, I now see, vary a lot. U can also sometimes get get coupons.
Were I to switch to free, given what I just saw on PC mag, I guess I would try the free Bitdefender I din know existed...

..... and with it, a highly rated free firewall.
It's confusing, right? U bet. Maybe you should experiment with free and monitor the results over time of this or that? You come across like someone who would be keen in observing.
No one app fends off everything or has 100% detection rate.
And again, I would never be without MBAM no matter what else I run.
