From Comodo Firewall, no harm at all. No need to remove it like Doodle said, this Comodo Firewall is very good in my opinion

Comodo Personal Firewall
Comodo Firewall Professional (Free) is the best firewall. It combines the simplicity of Kerio Personal Firewall with the functionality of Jetico Personal Firewall into an easy to use, elegant, and powerful firewall. Is hard to believe the software is free. They have several great free products, and are working on a FREE anti-virus, check it out (beta stage).

Necessary part of the Comodo Firewall, let it be or be unprotected
comodo firewall professional great firewall
Not recommended on old PCs because of the high CPU and HDD activity
My CPU was at 100% couldn't open database works 8, cmdagent.exe was at the top for memory use in task manager. Clicked Comodo updates and things back to normal, well database is for sure. Something to try.
cmdagent.exe has frozen my pc by utilising 100%cpu
  vic start  
Any system that locks up 99% of cpu with no hope of releasing is crap and should be deleted off the face of theplanet
This thing is using all the bandwidth of my internet! I can see it with a little program... Download: 100%.... I can't use internet to navigate...
This is part of the best, free Personal Firewall you can get, if you have COMMDO you have the BEST.
This is very good app! I use comodo internet security Premium best firewall I know and I use low speed internet air card. 'cmdagent . exe' connect the internet all time and decrease my internet speed 99.8%(too bad! ). If you have low speed internet, should not use this firewall app.
Part of Comodo Firewall
Appears to be associated with Verizon In-Home Agent
Comodo Anitvirus - Its the cloud scanner application.
  Tyler   (further information)
It's the active scanner for Comodo Firewall, part of Comodo Internet Security suite. Comodo's a great security suite and it's free to consumers, although at times it does hog resources, particularly on WinXP.
  Tom Q   (further information)
Also installed as part of Verizon's IHA_MessageCenter application for Windows 7
Even though it was allegedly a "trial" version of Comodo Firewall, something was wrong with the way it worked. Other scans + Security Taskman found major issues with this file, could have been tampered with or maimed as it ultimately did nothing. Took it off official Comodo Firewall site, yet it downloaded tainted.
Don't remove. It's part of Comodo Firewall program. Comodo is a nice Free Firewal
Comodo Firewall service. May conflict with Avast, causing high CPU usage. If so, disable HIPS feature.

Best practices for resolving cmdagent issues

A clean and tidy computer is the key requirement for avoiding problems with cmdagent. This means running a scan for malware, cleaning your hard drive using 1cleanmgr and 2sfc /scannow, 3uninstalling programs that you no longer need, checking for Autostart programs (using 4msconfig) and enabling Windows' 5Automatic Update. Always remember to perform periodic backups, or at least to set restore points.

Should you experience an actual problem, try to recall the last thing you did, or the last thing you installed before the problem appeared for the first time. Use the 6resmon command to identify the processes that are causing your problem. Even for serious problems, rather than reinstalling Windows, you are better off repairing of your installation or, for Windows 8 and later versions, executing the 7DISM.exe /Online /Cleanup-image /Restorehealth command. This allows you to repair the operating system without losing data.
