Computer question - re: Comodo and Cloud Scanner?

Do you have Comodo Firewall and if so do you get frequent “Cloud Scanner Alert: A malicious item has been detected.” I click on “clean” and get another pop up stating that not all of it could be cleaned and do I want to speak with live support. I always choose no.

Have you ever experienced this and if so what did you do about it? Did you speak with “live support”?

PS This is on my computer at work, not home, and we do not have an IT department.
