Sir: ... I, as well, use a 'MAC' Desktop exclusively ... THAT notification is NOT connected w/ 'MALWARE!' ...many "REPLIES" have associated exhibits / attachments / DVDs / etc., - - One must have Adobe Acrobat in order to use most any Web Site - - - BEFORE logging "IN" here at 'Dieselstop' - simply go directly to 'ADOBE' to download & install a legitimate, latest, free Copy or Version Lastly, consider a free application / download of 'Malwarebytes' for Mac ... it helps, too. ... ... THEN, come back here. Have a Great Day! - - - eliwhitneyI think the site may have malware. I keep getting a popup for Adobe Acrobat update on my mack. Some of them carry the Bing malware could admin check it out?
