Comodo taking up too much space on hard driver

My uninstaller program highlighted Comodo CIS as one the largest on my PC - indeed it uses 1.16GB of disc space in the programs folder - more than the whole Microsoft Office Pro suite! The only program larger is the Adobe CS6 suite. Is there anyway to clean the installation so that it does not take up this much space or is this a normal amount.

You may have some incomplete virus database updates. Check the scanners folder for duplicates. My entire CIS folder is about 425mb.
