Please help! I have never had any kind of anti-virus before and never had problem with my mac. But because its been suggested I should have them to protect my mac downloading music from LM I have installed free iAntiVirus and ClamXav.app softwares. Now I'm having big problem. My mac had been hacked I think by these free softwares just weeks after installing them. I now been told that those softwares actually harm your computer not protecting it.

I want to make sure that when I uninstall and delete them I get rid of all its files hiding in my mac. Is anyone knows what files name to look for and where to find them in my hard drive? Someone please help. Thanks.
