Malwarebytes has announced its first dedicated security download for Mac users in response to what the firm sees as growing concerns over increased Apple malware and adware attacks.
Malwarebytes Anti-Malware for Mac is free to download and is designed to detect and remove malware, adware and potentially unwanted programs.
Recently, strains of adware specifically targeting Mac have been discovered - including Genieo, Conduit, and VSearch - that inject ads and pop-up hyperlinks in web pages, change the user's homepage and search engine, and insert unwanted toolbars into the browser.
Marcin Kleczynski, chief executive of Malwarebytes, said that it is no longer the case that Mac systems are more protected from security attacks than others.
"The bad guys are writing trojans and ad pop-ups for the Mac," he warned. "Anti-Malware for Mac has been built from the ground up for the Mac environment - it's not just a simple port of our PC product."
The new Apple threat focus has been supported by Malwarebytes' purchase of Mac-based security company AdwareMedic.
The former boss of AdwareMedic, Thomas Reed, will now take up a role at Malwarebytes as the director of Mac offerings.
"Mac users need protection against what is becoming an epidemic of adware," said Reed. However, he did not share any statistics as evidence of this "epidemic".
A report released this year by software company Opswat found that only 50 percent of Mac users install antivirus products, compared with over 75 percent of Windows users.
"Windows users are much more likely to have at least one antivirus product installed on their device. This discrepancy could stem from the fact that many Mac users are not aware of the increased existence of Mac-specific malware," said the report.
The report also found that only 35.2 percent of Mac users had Real Time Protection (RTP) enabled on their systems.
"RTP is extremely important as it provides automatic protection by checking the user's device for malware and potentially unwanted applications," it warned.
Up to 1,800 strains of OSX malware were discovered in 2014 alone, as reported by security firm Kaspersky Labs.
"It's very likely that [hackers] honed their skills on the Windows platform first, and then went over to Mac to conquer new, uncharted territory in search of untapped money-making possibilities," said Eugene Kaspersky at the time.
