Live zilla

Hello,

I tried to install live zilla in site www.sinalizeweb.com.br , but something wrong happened, and I cannot unistall.

I took out the files in hosting, but I think the problem is in data base.
Can you help-me?
How can I unistall live zilla from the site?

Thank you!

You probably did not delete all files see check also folders under /administrator. Deleting component file will make joomla skip it's execution. Best if you get support from them we can only shot blind because we don't know that component, but generally it's unusual that any component can damage database, usually adds new tables .
