How to remove the DefaultView adware-type application from your system

What kind of application is DefaultView?

Our research team found the DefaultView application while investigating new submissions to the VirusTotal site. Upon examination, it became evident that DefaultView is adware from the AdLoad malware family. This app runs intrusive advertisement campaigns and might possess other harmful capabilities.

DefaultView adware overview

Adware stands for advertising-supported software. It generates revenue by feeding users with unwanted and potentially hazardous advertisements. This third-party graphical content (e.g., pop-ups, coupons, banners, overlays, etc.) can be displayed on visited webpages or other interfaces.

It is noteworthy that specific conditions may be necessary for this software to operate as intended (e.g., compatible browser/system, visits to particular websites, etc.). However, regardless of whether DefaultView delivers intrusive advert campaigns – the app remains a threat to system security and user privacy.

Adware-delivered ads can endorse online scams, untrustworthy/dangerous software, and even malware. Some of the adverts can carry out stealthy downloads/installations upon being clicked.

It is pertinent to mention that while legitimate products/services may be encountered through these advertisements – they are unlikely to be promoted by any official parties. This promotion is likely undertaken by scammers who are motivated to obtain illegitimate commissions by abusing the affiliate programs of endorsed content.

While AdLoad adware commonly possesses browser-hijacking functionalities – the DefaultView application did not exhibit such qualities during testing.

Additionally, advertising-supported software typically collects sensitive user data, and this might apply to DefaultView. Gathered information may include: URLs visited, webpages viewed, search queries typed, Internet cookies, log-in credentials, personally identifiable details, credit card numbers, etc. This vulnerable data can then be sold to third-parties or otherwise abused for profit.

To summarize, software like DefaultView may cause system infections, severe privacy issues, financial losses, and even identity theft.

Adware examples

We have analyzed thousands of adware samples; DiscoveryAdmin, IndexerAdmin, MetroBrowser, and IndexerTask are just some of our newest articles on applications within this classification.

Adware rarely looks illegitimate or otherwise suspicious – it tends to appear genuine and innocuous. Users may be lured into downloading/installing this software by promises of various "advantageous" functionalities. These functions seldom work as promised, and in most cases – they do not work at all. Remember that even if a piece of software operates exactly as advertised – that does not prove its legitimacy or safety.

How did DefaultView install on my computer?

Adware can be bundled (packed together) with regular programs. Downloading from freeware and free file-hosting websites, Peer-to-Peer sharing networks, and other suspect sources – poses a threat of bundled content infiltrating the device. This is compounded by rushing through installation processes (e.g., ignoring terms, skipping steps, using "Easy/Express" settings, etc.).

Additionally, adware is endorsed on legitimate-looking promotional webpages and scam sites. They are predominantly accessed via redirects caused by websites using rogue advertising networks, intrusive adverts, misspelled URLs, spam browser notifications, and installed adware (with browser force-opening abilities).

Advertising-supported software is also spread by intrusive ads. Some of these advertisements can be triggered (i.e., by being clicked) to execute scripts that perform downloads/installations without user permission.

How to avoid installation of adware?

It is essential to research software before downloading or purchasing it. We recommend downloading only from official and trustworthy channels. When installing, it is important to study terms and options, use the "Custom/Advanced" settings, and opt out of all additional apps, extensions, features, and so on.

We advise vigilance when browsing since fake and malicious online content typically appears harmless. For example, despite their ordinary/innocuous appearance – intrusive adverts redirect users to unreliable and questionable websites (e.g., pornography, scam-promoting, gambling, adult dating, etc.).

If you keep encountering ads/redirects of this kind, check the device and immediately remove all dubious applications and browser extensions/plug-ins. If your computer is already infected with DefaultView, we recommend running a scan with Combo Cleaner Antivirus for macOS to automatically eliminate this adware.
