Macs impervious to Malware? Think again.

In the past, before the rise of Apple that began at the turning of the Millennium, it was quite rare for Apple’s computers to be the targets of viruses, trojans, worms, and other types of malware. Those were usually reserved for the Microsoft Windows platform, more popular at the time and less controlled than the MacOS.

However, in today’s times of the internet and the popularity of Apple, there’s greater risk of being susceptible to attacks from malware. These attacks usually occur when accessing links or files, such as clicking on ad banners online, downloading software from crowd-sharing means such as through torrent files, and clicking on attachments in emails, even if those emails are from known sources.

One recent malware called “Searchmine.net” is an example of malware that infects the MacOS. It targets web browsers such as Chrome, Safari and Firefox. The malware has the ability to change the browser’s homepage, new tab page or default search and take measures to prevent users from changing those settings back. This can allow the malware designers to track users’ browsing habits, and target them with customized ads, or sell this information to 3rd parties.

Unfortunately, accessing the location where the application is installed and removing it will not cure the issue, as this malware is persistent. Scanning with an application like Malwarebytes, frequently used to assist in detection and removal of items such as this, will be fruitless as well, as Malwarebytes has difficulty detecting the application. With Malwarebytes being ineffective, the next step of researching online for other tools to remove Searchmine can reveal potential solutions. However, some of these “solutions” could actually be additional malware that cause additional problems. And they are not inexpensive to use, even if they don’t have bad intentions and actually solve the problem.

For users of the Chrome browser, a recent tool developed by a product expert appears to remove the malware through the running of a script in the MacOS Terminal application. The Terminal application is a way to run processes and navigate the Macintosh file structure through a text command line interface. This script method has been shown to work. Instructions on its use can be seen at this link. If you have questions on its use or need assistance, don’t hesitate to contact us.

As for users of Safari and Firefox, the solutions don’t appear to be as clear. It is best to contact us to ask questions or have us address the issue . As a general tip for users, it is a smart move to not download files from sources that are not trustworthy. Also avoid clicking on banners on sketchy websites, and beware of clicking on email attachments, especially from untrustworthy sources.
