Half the battle in avoiding adware intrusion on your device is reading install wizards and EULAs with hawk-eyed precision.Ī pre-checked box and a tiny EULA screen spells adware Adware makers trick users into willfully downloading programs they won’t like by pre-populating check boxes, greying out or minimizing options to skip, or plastering “recommended” next to a preferred option one-too-many times. The common theme among these delivery methods is deception. It’s even making its way into the Google Play Store- with more frequency these days-and blessing Android devices with its garbage content. Often, it shows up in downloaded files from torrents or piracy sites.

Adware may also hide inside a legitimate download from an unethical site. The most common ways for adware to infect PCs today are through toolbars/browser extensions, bundled software, and downloads offered by pop-ups.Ī Trojan containing adware may pretend to be something you want, such as a plug-in or video player, but what you really end up downloading is an adware installer. Thankfully, the cybersecurity industry is making strides in courtroom battles and in public opinion against software providers whose programs cross the line from slight bother to major asspain.

Unfortunately, since most people aren’t paying close attention to what they download, they essentially agree to install the programs without realizing it.Įven more unfortunately, any attempts by security companies to fully block these programs as malware can get legally hairy. Security companies flag these programs as “potentially” unwanted, but the reality is, any sane person would not want this crap on their computer.

PUPs also include other borderline malicious programs, such as spyware, browser lockers, dialers, and junkware. How is adware different from PUPs?Īdware is, essentially, a type of potentially unwanted program. This is what makes adware a type of potentially unwanted program, or PUP. Whether you download adware without full knowledge of what you’re getting or whether it hides in the EULA of another software program like a stowaway, it’s behaving in a way that neither you nor the software it latches onto wants. Adware, in contrast, is specifically designed to be a nuisance, sneaking its way onto people’s systems by bundling up with legit programs or disguising itself as something else.

When legitimate software applications use online advertising, the ads are typically bundled within the program and designed and displayed in ways that the developer specified-and a good developer knows not to piss off customers with overbearing ads. Why would anyone knowingly install a program that behaves this way? The answer is: They wouldn’t. Have some toolbars, courtesy of Mindspark adware.
