I have a malware that sophos doesn't seem t obe able to remove. I run it several times at one time it said it was all removed, then I can see the computer is acting out and the malware is still there.

I have a malware that sophos doesn't seem t obe able to remove. I run it several times at one time it said it was all removed, then I can see the computer is acting out and the malware is still there. All my files went to the trash by itself when I only removed sophos to reinstall it. In one of the pass it wrote "REmove any extension instaled by InstallCore into Safari and then Aliases: gen.variant.Adware.MAC.OSX.GenieoCA.I and two others.Anyone knows what this is. Thank you

Could it be possible that my  IP address has been target? I appreciate any thoughts on that.
