Since when Comodo adds junk to its installers? If you are referring to their assistance program, then I see that far from being junk.
Many users are not fully aware in how to remove infections. Users do use Comodo Geekbuddy.
If you look at 90% of the security suites, you will not see the option upon installation to disable/enable everything.
Mamutu is a known standalone Behaviour Blocker and pretty much the only one left in the market. Another good one was TreatFire.
There is nothing wrong in having users wanting to run additional Tools to complement others. That is call being efficient.
I do not say comodo is not good. It is good, but since when a product is 100% perfect?
Seems like there are comodo haters in here. Either that or users who simply believe in one product.
