Remove Ad Malware Safari El Capitan I used to have 10.11 yesterday when I saw multiple ads from multiple sites opening when I'm viewing webpages using Safari. I updated to the latest version of the OS, 10.11.6 but it hasn't fixed the issue. I've restarted the OS multiple times. I've tried MalwareBytes as it was suggested in forums. I also tried removing all safari data from Library folders to reset Safari and it still hasn't fixed the issue.
The malware redirects websites I visit to offerland.info / bestphoneapps.mobi / mobrevflwms.com and many other sites.

Solutions would be appreciated.

MacScan 3 - [Subscription $50 pa] with free trial. idk whether the free trial will let you actually remove anything it finds. Prime task is to remove bad cookies. I've been using it since v1 &amp; have never 'caught' anything it couldn't kill, though that in itself doesn't prove it will kill everything, only the ones I've seen.

For an actual 'antivirus' - rather than me post a list, it would be better to refer you to AV-TEST, which is the closest thing to an actual authority on the subject, or specifically their most recent Mac report . As of their last report, July 2016, they list 4 products with a 100% hit-rate, yet only two which can do that without leaning on your machine &amp; slowing it down, BitDefender &amp; ESET. Neither of those are are free.  

They update the report twice a year, so the main link should remain usable in future, as the specific July 2016 report falls out of date.
