On my new Dell 690 Workstation, both Comodo Firewall or Webroot Spysweeper seem to work fine alone. Enabling them both, however, produces 100% CPU usage with each claiming about 40% of the total cycles. I also experience frequent lockups, apparently caused by them. Are there known incompatibilities between these two?
I have not heard of any incompatibilities. I did find this post regarding start up:
Are there entries in your firewall log relating to spysweeper: perhaps CFP is blocking some activity of spysweeper and creating a lot of log entries?
Also, you could try ticking the skip advanced security checks box for spysweeper entries in your application monitor.
Thanks for the suggestion. I didn’t think to check the log. There are thousands of log entries related to “Application access denied” for something called C:\Program Files\Dell SAS RAID Storage Manager\Megapopup\popup.exe, whose parent application is Explorer.exe, seeking TCP in at 0.0.0.0:53323. I have no idea what this is, but apparently it has nothing to do with Spysweeper. Any suggestions?
Here is some info on the RAID storage manager:
This may be useful too:
By selecting Start>System>More Programs>Dell SAS RAID Storage Manager on your pc you may be able to find out more about this application or configure it so it does not conflict.
I am not sure if you need to have this running but you could use msconfig to look for startup entries and disable them but you would be better asking Dell or finding out more about the application before doing this.
Meanwhile you could change logging of the firewall to try and improve things:
In network monitor right click any block and log rules and select edit. Uncheck the box ‘create an alert if this rule is fired’ and click ‘OK’.
You can always turn this back on later if you wish.
An alternative option which can help and will still allow you to view some log events is to make the log file itself read only:
Log Files usually at: C:\Documents and Settings\All Users.WINDOWS\Application Data\Comodo\Personal Firewall\Logs
Right click the file and make it read only. This drastically reduces the drain on your system in most cases.
