cavs proxy sevr and comodo firewall

hi,i have just installed the av module,having already had the firewall.
i keep getting alerts from the fwall saying cavs proxy sevr is trying to make outward connection and the trying to accept incoming connection.
the fwall keeps saying this process is suspiciously generated and recomends not allowing(in as many words).
is this a legit request from this proxy sever app via comodo av?.

also since installing the av i have been getting regular nvidia power warnings for my 6600gt card even tho there is good voltage to it,would there possibly be a clash of software here.thanks…
