Malware, short for malicious software, is software designed to disrupt computer operation, gather sensitive information, or gain unauthorized access to a computer system.
Malware includes computer viruses, worms, trojan horses, spyware, adware, most rootkits, and other malicious programs.
Mac and Windows users can fall victim to adware. The easiest way to avoid pop-ups and other annoying ads is to stay away from torrent applications such as uTorrent. Sites that offer streaming and downloading of movies at no cost that are not free to distribute are the most common source of adware. If you are asked to install a browser extension or a player to view online content be suspicious.
Mac users - Two known items that bring many Mac users to the Help Desk for adware removal are Geneio and MplayerX.
Geneio is a very popular site that is a known source of adware for a Mac. When it becomes the homepage in your web browser you most likely have already fallen victim to adware.
MplayerX installed from anywhere other than the Apple Store is a known application bundled with browser extensions and login items that generate unwanted ads and other annoyances on a Mac. Please do not think you are safe from malware because you are using a Mac. It is far from true although the malicious stuff is not as broad as it is for Windows users. The UDit Help Desk has seen dozens of Macs this semester infected with adware. $50 to clean your Mac becomes pretty expensive for that free movie. Is it worth risking your academic success to be without your computer for a day or more?
