today my antivirus, avast,warn me that my comodo firewall has a prorat trojan. what should i do ? is it possibile that comodo could have a ‘‘rat’’ ?
ps
sorry if my english sucks. i`m not from england. 
That must be a false positive by Avast. It is best to report this with Avast.
Funny, I uploaded a bunch of Rat programs recently (incuding prorat and it’s variants) . Do you think avast is detecting the comodo virus signitures???
