avast firewall doesn't work on my phone

[MaxReed]

Hi everybody!
I have a samsung galaxy y duos gt-s6102 and I've installed avast mobile security and anti theft, but the firewall doesn't work.
When I go to active it, it asks me the root permission and I accept, next it tells me that netfilter isn't compatible with my kernel....
What can I do? I need it, my phone have consumed all money on my first usim

Thanks to all!!

Hi,

you have to update your OS. If there isn't an official update available, your only option is to flash a custom ROM with netfilter support.

i have updated the os and i can't install a custom rom because there isn't a custom rom that support the dual sim sistem.

[Filip Havlicek]

Then you are out of luck I suppose You can always compile your own ROM, but if there aren't any custom ROMs with dual SIM support, I suppose there aren't any such sources as well.

there isn't any (simple) way to add manually the file necessary to support netfilter,without damaging or modifying excessively the os?

[Filip Havlicek]

I think the kernel needs to be compiled with the netfilter support, it's not just about adding a file here or there.

first of all have you rooted your fone
if no it wont work
if yes check if firewall is getting all needed permissions

this software can help you in granting needed permission

I've already rooted my phone, I already have superuser and avast have root permission...
how I explained in my first post, when i go to active on firewall, avast take the root permission but tells me that my kernel isn't compatible with netfilter

I think the kernel needs to be compiled with the netfilter support, it's not just about adding a file here or there.
