Comodo Secure Shopping

Hi, I write from Italy, and excuse my English.
Sorry if I got the wrong thread.

Unfortunately I had to uninstall CIS for incompatibility with a cheap HP notebook.
Three installations, a month of tests, and three uninstallations.
I will use CIS on the other (less economic) computers in which it works very well.

My question: Comodo Secure Shopping has a different uninstall.
But although I have uninstalled CIS, can I continue to use Comodo Secure Shopping in perfect security?
Or is it preferable to uninstall it?

Thanks and regards from Italy.
