Avast says I have RelevantKnowledge malware... How do I remove it? Avast Browser Cleanup claims it is finding an unwanted toolbar protector called RelevantKnowledge. I tell it to remove it, but then when I reopen it gives me the same message. What is going on? I cannot actually find it anywhere on my computer. MBAM Threat Scan did not find it anywhere. I searched my harddisk for rlvknlg.exe, and nothing was found
