It's a PestPatrol Real-time service from CA Antivirus. You can disable it with services console.

itmrtsvc.exe is a eTrust PestPatrol Real-time service from CA, Inc. belonging to eTrust PestPatrol Realtime Protection
it is part of the e-trust antivirus program as stated
Significantly slows down my computer. I can kill the process, but then my "CA Security Center" (antivirus, antispyware, antispam, firewall) says it the antisyware need attention.

came with Road Runner CA software install
It hides itself so you can not easily uninstall it. It can cause memory problems. If the program is what it says it is it is considered safe, but the name is often masked by malware. Removing the program is extremely difficult and often requires booting in safe mode to delete the files, followed by a registry cleaning application to clean the registry traces.

This is a Control program installed as part of COMCAST AntiSpy Service. You can uninstall it fromt the Control Panel look for CA or similar listed
Norton Security Suite blocks it regularly whenever the computer is on. Severity: medium Activity Unauthorized access blocked (access process blocked) It does seem to slow things down and it keeps trying to connect. I do have Comcast so it could be as stated above and be part of the Antispy Service. C:\PROGRAM FILES (x86)\CA\PPRT\BIN\ITMRTSVC.EXE
superantispyware, malwarebytes, or Norton have never identified it on my pc. I have wndows 8.1, use comcast, watch videos and play games online, and believe me I know how to get a virus, malware, Trojan or worm. I also know how to get rid of them. As far as I can see, ITMRTSVC.exe is safe. However should I find out different, I will be glad to let you know.

Best practices for resolving ITMRTSVC issues

A clean and tidy computer is the key requirement for avoiding problems with ITMRTSVC. 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.
