The first time i used Comodo Internet Security is very good!
I was used to a famous antivirus program to protect my computer, but always have problem with their subscription, i am sure my subscription is not expired yet.
After i checked, it's look like some virus attack their subscription status, so my antivirus software doesn't work.
I like the Comodo Internet Security because it's easy to used, not reduce my computer speed, alert my what to do with unknown program, secure my computer from internet attack (i see the log that some site try to attack my computer), integrated antivirus and firewall seem don't have any hole right now and of course it's free
I refer this program to all my family, and now they used this program.
