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.
What does Application.MAC.OSX.Winjack do
Actually, most of the unwanted applications are not actually dangerous, however, they can easily cause chaos into the system. If Application.MAC.OSX.Winjack infiltrates your Mac, it can slow down its performance significantly and make your browser unresponsive to your online activities.
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.
To avoid installing unwanted applications onto your Mac, we advise you to download free software from developers’ websites only and pay close attention to the installation process you are going thorough. Don’t trust any Torrent websites or pop-up ads offering you software updates because they could easily deceive you and infect your computer with malware.
Also, make sure that you have installed a reliable antivirus software onto your Mac and make regular security scans to keep it safe at all times.
