the problem is with avira not comodo, they are doing something different and they need to fix it.
Since almost 4 years, I'm loyal to Comodo Firewall free plus Avira AV Free on 9 PCs and laptops.
However, I observed during the recent Avira 13 upgrade, it still pops a dialog box asking to remove Comodo. But, as usual, I always ignore it and proceed for Avira installation on top of Comodo.
a) why this issue still happening? will this affect the functionality of either programs?
b) how to *know* my firewall is not getting messed up by Avira and vice versa
ps: I'm still using Comodo 5.10.x Is this good enough for a typical home requirement?
