port 28

Greetings !
I have just started using Comodo av and firewall and it’s great !
One question tho’ on Sheilds Up port 28 shows Amanda Trojan and port 30 shows Agent 40421 Trojan when moused over. Should these not be detected on av scan? And is there a way to remove these pests ?
Once again, thank you for a great all in one product.
