You can bypass a vac ban depending on the sort of ban(I'm still able to do it last time I tried).

I'm gonna try it now again and see if it still works after a loooong time :P
As the title says, i am VAC banned from MW3.
What options do i have if i still want to play MW3 online? I remember AlterIWNet, but thats a while ago..

The tool only works if you got banned a looong time ago. If you cant connecto to online services this means that you've got banned to late. If this is the case your only option to play steam mw3 is to buy it agin on a different account.
You can also try Teknomw3, it is pretty much the same as alterIWNet.
