I have never known a security product which has continually upon every “fix” caused so many problems to users. I have used Comodo for several years and paid for the professional versions but have now uninstalled them all due to too many issues which simply do not exist with other products. I put it down to very poor quality control and Melih’s relentless push to try and keep up with Norton and others in terms of functions - which is great in one sense - but at the end of the day CIS is still unreliable and causes a high overhead for the advanced users, in my experience, as well as not being a “set and forget” solution for the average user. Myself, I am successfully now using the excellent, simple Privatefirewall with Malwarebytes Professional and MSE. What am i doing here? Just occasionally checking and hoping that finally one day my beloved Comodo will fix their quality issues!!! :-TD
