What is Application.MAC.OSX.Winjack

Application.MAC.OSX.Winjack falls into the category of potentially unwanted applications (PUAs). These programs are capable of infiltrating your Mac without asking you for any permission. Considering this fact, Application.MAC.OSX.Winjack should be instantly removed from the system as it can seriously threaten your online security.

How is Application.MAC.OSX.Winjack distributed

Most often, Application.MAC.OSX.Winjack enters your Mac via fake downloads. For example, if you are updating your Flash Player, the PUA might enter your computer bundled with the update without your knowledge or permission.

Be aware that Application.MAC.OSX.Winjack uses software download portals to infiltrate your Mac. Usually, software download portals use ‘installers’ that bundle potentially unwanted applications with free software to enter your computer. Thus, you should always download programs from the official App Store and not trust the updates offered by any other websites.

Also, in case your Mac displays a message saying that a virus is found, DO NOT trust it! There is NO website which can determine if your computer is infected with virus or not. Only your anti-virus software can do it. Any other messages of this type are fake and they’re likely to distribute malware.

Another common method of distributing potentially unwanted applications are disk cleaning apps. They install on your Mac, set themselves to start automatically on each system startup, and start performing fake system scans which detect many issues. To fix these issues, you are asked to fill in your card details to pay for the license of the program, which is a serious threat for your financial security.

The PUA is also capable of flooding your screen with numerous commercials and pop-ups whose main purpose is making profit for their developers. Keeping in mind this fact, you should be very careful about the software you install on your computer and remove all the unwanted applications as soon as you notice them.
