Windows 10 issue

I apologize for criticizing Comodo earlier today. I could find the issue which was blocking Comodo from working on the new version of Windows. Actually Windows was trying to force us to use just their software (windows firewall and windows defender keeps turning on every time I turn the PC on) I had just to turn on develope mode on security (click on notifications at taskbar/all settings/update & security/for developers/select developer mode). I also truned off windows firewall and windows defender I pretend to block with Comodo. It is working fine now.

Excellent Features

The Internet security features hosts some of the key features like Default Deny Protection that makes the product stand out from the other security products in the market and it is good to serve the purpose, it simply defends unknown threats

Some issues

nice antivirus but the program have problems with interface... freezing image to much time...anny theme i used... the antivirus window freezing...i use win 7 ..thx

It is not what I expected

Facing quiet a lot of issues with the product, one good thing about Comodo is its support team.

Best Virus Protection and firewall on the Market

I have been using comodo product for several years and have never had any problems on Windows 7 64bit / 8.1 64bit. Installation was easy and first-time scan took less than 5 minutes (obviously that can change based on your CPU and drive speed). I love its simple intuitive interface. At this cost you have no excuse for not protecting your PC. Comodo could be bit complicated for people who are not familiar with the terminology or usage of the program. But it is still an excellent product. I highly recommend it.
