owers (Mozzella) ? (Sorry not sure what that means). Do you mean Mozilla Firefox is redirected? I moved this to Malware Discussions as that is what it appears to be about..
What is your operating system (and service pack if applicable) and is it totally up to date?
Can you try to use System Restore to go back to before all this started?
Also try some of the tools in the last link in my signature below. Stinger and Malwarebytes Free to start with would be a good idea.
