Hi, I had been using Avast, and since yesterday (IST), I am using Comodo. I know Comodo from the very past as I had been using your Firewall. One quick question. My system performance was bit low as I had quite a lot of stuff installed, downloaded. After installing Comodo Antivirus, I see that system is doing too poor and also the CPU usage shoots up very high. Not sure, where is the problem. Also I am unable to install Comodo Firewall after having installed Comodo Antivirus.
If you did not do it already, uninstall avast from Control Panel (if possible). If, for any reason, you can’t run it, try booting in Safe Mode and doing it from there. Anyway, boot after that.
