I have been using the Comodo Internet Security for less than a month, installed it when I reinstalled my Windows(7 Home Premium). It has worked good, but ever since I installed it I notice that occasionally the cmdagent.exe process starts to take a very large amount of my CPU, with no apparent reason. It goes from 0% to 90%, intensively for short periods of time and only stops when I shut down every single application I use and give it a minute or two idle time.
I have no idea what causes this, as I don’t have a lot of software on my computer, everything is legit, I got absolutely no spyware, viruses, trojans and etc.
It can’t be overheating either, because I am using a Dell laptop and I additionally bought a Belkin cooling pad, that is really really good, so the fault must be in the Internet Security software. There is no other explanation, as this process starts taking up the large portions of CPU randomly, not when I start a certain application/s.
What could be causing this? Perhaps it is some configuration I missed? Everything is set to pretty much default settings, I have no sandboxed programs and no suspicious software.
There is no other process taking that much of my CPU, ever.
Forgot to mention that my HDD isn’t full either, got over 40% available.
You are using an OEM laptop that most likely came with a preinstalled security program from Norton or McAfee.
Start with remembering what security programs you had installed before you ever started using CIS.
Nest step is to make sure that there are no left overs of previously uninstalled security programs around. Not all uninstallers do a proper job. And left over applications, drivers or services can cause all sort of “interesting effects”.
Try using removal tools for those programs to remove them. Here is a list of removal tools for common av programs: ESET Knowledgebase .
Thank you for the reply, but I haven’t used any other security programs on this installation. As I said - I reinstalled Windows recently, and I installed CIS straight away.
There was no antivirus software preinstalled once I finished the installation, which I made using the provided by the Dell along with my laptop CD.
The only security things besides CIS are Windows Firewall and Windows Defender, which I think are disabled and their Comodo counterparts are in use.
The Database set to update in real time scanner settings, updates at system start and then a regular intervals.
This could cause some lag soon after booting the system especially if it has not been used for some time as then the updates have to play catch up.
Having it disabled will not compromise your security and just to be safe manually update it once or twice a day.
