Then many pop-ups, so little time.

Looks like mom's got adware.

What is adware?

Adware is curt for advert-supported software. It'southward well-known for being a major Mac nuisance and has made itself ubiquitous on Android OSes, finding its manner into the Google Play Store as Trojanized apps.

But adware is a PC trouble, too. It delivers ads and other browser-cluttering junk virtually oft in the form of popular-ups, tabs, and toolbars. Beyond simply bombarding you with ads, adware tin can hijack your browser, redirecting you to sites y'all weren't planning on visiting (and showing y'all ads there) or delivering random, back-alley search engines results.

Why would anyone knowingly install a program that behaves this way? The reply is: They wouldn't. When legitimate software applications employ online advertizing, the ads are typically bundled within the program and designed and displayed in ways that the developer specified—and a good programmer knows not to piss off customers with overbearing ads. Adware, in contrast, is specifically designed to be a nuisance, sneaking its fashion onto people's systems by bundling upward with legit programs or disguising itself every bit something else.

Whether you download adware without full knowledge of what you're getting or whether it hides in the EULA of another software programme like a stowaway, information technology's behaving in a way that neither you nor the software it latches onto wants.

Security companies flag these programs as "potentially" unwanted, but the reality is, any sane person would not want this crap on their computer. Unfortunately, since most people aren't paying close attention to what they download, they essentially agree to install the programs without realizing it.

Even more unfortunately, any attempts by security companies to fully block these programs as malware can get legally hairy. 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.

How do you lot get adware?

The most common ways for adware to infect PCs today are through toolbars/browser extensions, bundled software, and downloads offered by pop-ups.

A Trojan containing adware may pretend to be something you want, such as a plug-in or video player, simply what you lot really end upwards downloading is an adware installer. Adware may also hide inside a legitimate download from an unethical site. Oftentimes, it shows upwardly in downloaded files from torrents or piracy sites. Information technology's fifty-fifty making its way into the Google Play Shop—with more frequency these days—and approval Android devices with its garbage content.

The common theme among these delivery methods is deception. Adware makers trick users into willfully downloading programs they won't like by pre-populating bank check boxes, greying out or minimizing options to skip, or plastering "recommended" next to a preferred option one-too-many times. Half the battle in avoiding adware intrusion on your device is reading install wizards and EULAs with militarist-eyed precision.
