Stick around until the end of this blog to find out how to make informed choices and how investing in robust IT solutions is the key to a safer and more secure online experience.

What Can Malicious Adware Do?

Adware (in cyber security), a form of malicious software, covertly implants itself onto your device, orchestrating the unwelcome display of advertisements and pop ups (adware). In more intrusive instances, malware adware has the capability to monitor your online activities, tailoring its ads to your preferences. Derived from the term “advertising supported software,” it is crafted to inundate your screen with ads, frequently infiltrating web browsers. Some cybersecurity experts consider adware as a precursor to contemporary Potentially Unwanted Programs (PUPs). Typically employing deceptive tactics, it either masquerades as legitimate software or exploits another program to deceive users into unwittingly installing it on their PCs, tablets, or mobile devices.

Navigating the online realm can turn chaotic when adware disrupts your browsing experience. This intrusive software generates revenue for developers by bombarding users with unwanted ads, often interrupting activities and redirecting browsers. Attempting to close these ads becomes futile as they persistently reappear. An adware attack infiltrates your device, altering settings, changing homepages, and presenting dubious content, ranging from fake weight loss programs to get-rich-quick schemes. Even legitimate software may unwittingly harbor adware. While not inherently harmful, adware poses a nuisance, analyzing your online behavior to tailor ads. Recognizing signs such as unexpected ads, homepage changes, and sluggish browser performance is crucial in detecting and addressing viruses (adware).

How Does Adware Work?

Adware employs two covert entry points to infiltrate your system. Initially, it discreetly installs during the download of seemingly innocent freeware or shareware, facilitated by the program’s author partnering with an adware vendor. This collaboration subsidizes the free distribution of the software, but users unwittingly bear the cost through intrusive ads. The second method operates subtly as well, exploiting vulnerabilities in web browsers during website visits. Trusted or dubious sites alike may harbor adware, initiating a drive-by download that, once embedded, collects user data, redirects to malicious sites, and inundates browsers with additional advertisements. Both methods underscore the hidden repercussions associated with seemingly cost-free or routine online activities.

Types of Adware

In its various attempts to infiltrate your PC or device, adware frequently adopts the guise of browser hijackers, specializing in surreptitiously altering Internet browser settings. These intruders, operating without user knowledge or consent, typically manipulate homepage and default search configurations. Despite seemingly originating from the visited site, the barrage of ads that ensues, often in the form of pop-ups or pop-unders, is actually orchestrated by the adware. Certain programs go beyond browser settings, impacting start pages, search engines, and even shortcuts on the device. Adware exhibits diverse forms tailored for specific devices and operating systems, ranging from mobile/Android adware to Mac and Windows variants.

History of Adware

In the early years, around 1995, the tech industry regarded the first ad-supported software as a subset of spyware. Adware (spyware) was initially seen as a less harmful form of Potentially Unwanted Programs (PUPs) and even considered “legitimate” when created by legal businesses. However, affiliates of these businesses distributed adware unchecked, leading to widespread proliferation through peer-to-peer sites, botnets, instant messaging infections, and browser hijacks. Adware vendors eventually began shutting down unruly affiliates, disavowing responsibility. In the peak adware years (2005-2008), hefty fines were imposed, causing major players to exit. While adware persists, it’s now viewed as a lower-level threat, but its volume is increasing, driven by mobile device proliferation. Modern adware employs aggressive techniques, hiding within Trojans, bundling with adfraud components, or demonstrating rootkit capability, making removal challenging.

Mac Adware

Historically immune to adware concerns, Mac users enjoyed built-in anti-malware protection and were considered a less attractive target for cybercriminals compared to Windows PCs. However, this landscape has rapidly changed. New Mac malware families surged by over 270% in 2017 compared to 2016, marking a notable shift. Mac-specific adware emerged in 2012, proliferating through both clandestine efforts by hackers and seemingly legitimate corporations embedding adware within fine print of installation agreements. Often riding within Trojans, Mac adware presents symptoms similar to Windows infections, such as pervasive ads, unauthorized homepage changes, and erratic webpage behavior. While Macs are less vulnerable, addressing adware security issues becomes imperative.

Mobile Adware

In the confined space of a mobile screen, the sudden appearance of unfamiliar icons or an influx of ads in the notification bar signals the unwelcome presence of adware. With thousands of Android apps now harboring this intrusive feature, mobile users face two main avenues of adware infiltration: through the browser or downloaded applications.

Browser-based infections exploit known vulnerabilities, often triggered by JavaScript code handling redirections. Switching browsers, disabling JavaScript, or using ad-blocking browsers helps mitigate pop-ups. Downloaded applications, particularly from third-party app stores, may introduce persistent adware apps. Caution with third-party stores is advised, as even Google Play can inadvertently host adware-infested apps.

While adware is typically more of a nuisance than a direct threat, users should weigh the annoyance against the potential benefits of free apps that rely on third-party ad content for revenue. Despite its bothersome nature, adware is generally not as malicious as malware, emphasizing the importance of making informed choices between adware-laden free apps and paid alternatives that offer a smoother experience.

Who Do Adware Authors Target?

Common belief suggests that adware primarily targets individuals rather than businesses, infiltrating various platforms such as Windows PCs, Macs, mobile phones, and virtually all browsers. Operating under the guise of the “too good to be true” model, adware entices potential victims with promises of free games, movies, or exclusive deals in a deceptive scheme that spans across diverse opportunities.

How to Remove Adware?

If you suspect that your Mac or Windows PC has fallen victim to adware, there are steps you can take to address the infection. Begin by regularly backing up your files. Attempt to remove the adware through the relevant utility on your operating system, such as Add/Remove on Windows. However, identifying the adware program’s name is crucial, and some adware may have files that can revive the program after uninstallation.

If removal proves challenging, download a reputable cybersecurity program. These tools are designed to detect and eliminate adware, PUPs, and emerging malware threats. Conduct a thorough scan, and if any threats are detected, the program will eradicate them. Subsequently, consider changing your passwords not only for your PC but also for email, social media, online shopping sites, and billing centers for enhanced security.
