I work with the computer at home. Will Comodo automatically delete or ask?

No problem glad i could help. Before installing comodo please remember to clean up files left over by previous antivirus software this can prevent some problems later on.

4.Clean Any Remnants Left From Former Security Products
If you ever had a different security program installed before you tried uninstalling CIS, then part of the problem could be due to interference from their leftover files. To ensure that this will not cause a problem please run the removal tool for each of those security programs that you used to have installed. A list of uninstallers for common antivirus software, can be found on this page. Please select the ones for any security programs you previously had installed and run them.
