Hi guys,
check for this code on your respective sites:
carolschaufel.com: <style>.mnz0{position:absolute;clip:rect(468px,auto,auto,481px);}</style>
duo2tek.com: <style>.cxo3{position:absolute;clip:rect(487px,auto,auto,419px);}</style>
What this does is it hides div with class mzn0 (or cxo3), which includes spammy links. Deleting the code above should make the spammy links appear on your website, and also make Avast stop flagging your websites.
