Which icon?. What does is say when you put your mouse pointer over it, or right click on it?

It's probably a TRS loaded at boot time and if it is your firewall icon (usually a shield type shape), you don't want to get rid of it.

If malicious software is a concern, try running an 'on-line' scan such as Trendmicro Housecall... can take a long time on large heavily loaded hard-drives!
