Hi Nasdaq,
Thanks for your follow up. I have tried your suggestions. No Luck. MBAM and AdwCleaner find no threats. Yet many websites are still plagued by Retumal.com. (MBAM blocks this successfully, but cannot remove the annoying source) I have followed steps 1 & 2 in the link below. No suspicious programs show up in Windows Programs and Features. I have not yet tried step 3 (Hitman) . I have tried, several times, to reset Chrome to Default Settings with mixed results. I have not yet tried Step 5 (Zemana).
