Delay in using computer

I seem to have to wait 10-15 seconds everytime I log onto my e-mail, or even a web site before the keyboard is functional. The hard drive is constantly running during this time. Anyone else experience this with comodo?

What version of Windows are you using?

In Task Manager, could you let it sort on disk usage and see what process is causing a lot of HD traffic? You may need to select various columns about disk usage under View → Select columns.
