How to remove MegaUnit adware and the advertisements it delivers?

Also Known As: Ads by MegaUnit
Type: Mac Virus
Damage level: Medium

What is MegaUnit?

MegaUnit is an adware-type app with browser hijacker traits. Furthermore, due to the dubious methods used to distribute software products within these categories, they are also classified as PUAs (Potentially Unwanted Applications). MegaUnit has been noted being proliferated via fake Adobe Flash Player updates.

MegaUnit adware in detail

Adware enables the placement of third-party graphical content (e.g., pop-ups, coupons, banners, etc.) on any visited webpage and/or different interfaces. The displayed adverts diminish the browsing experience and endanger device/user safety.

Intrusive advertisements promote various sale-oriented, untrustworthy, rogue, deceptive, and even malicious websites. Furthermore, some of these ads can stealthily download/install software (e.g., PUAs) - when they are clicked on.

Browser hijackers reassign browsers' homepage, default search engine, and new tab/window URLs - to fake web searcher addresses. With such a piece of software installed: new browser tab/window opened and search query typed into the URL bar - redirect to the promoted search engine.

Illegitimate web searchers usually cannot generate search results, so they redirect to Yahoo, Bing, Google, and other genuine search engines. What is more, browser hijackers also use persistence-ensuring techniques to prevent users from restoring their browsers.

Most PUAs (adware and browser hijackers included) can track data. Targeted information includes browsing and search engine histories, IP addresses, personally identifiable details, and so on. The collected data is then shared with and/or sold third-parties.

In summary, the presence of unwanted apps on devices can lead to system infections, severe privacy issues, financial losses, and identity theft.

Adware in general

OptimalSourceAnalyzerWindow, and PortalFlow are a couple examples of adware. Like most PUAs, this software appears legitimate and offers "handy" features, which are typically nonfunctional. Instead of delivering on any promises, unwanted applications can run intrusive ad campaigns, cause redirects, hijack browsers, and collect sensitive data.

How did MegaUnit install on my computer?

PUAs are distributed using the "bundling" technique - packing regular software with unwanted/malicious additions. Rushed downloads/installations increase the risk of allowing bundled content into the device. Intrusive adverts proliferate PUAs as well. Once clicked on, the ads can execute scripts to make stealthy downloads/installations. Some PUAs may also have "official" promotional/download sites.

How to avoid installation of potentially unwanted applications?

It is important to research software and only download it from official/verified sources. Untrustworthy download channels, e.g., unofficial and freeware websites, Peer-to-Peer sharing networks, etc. - often offer bundled and harmful content.

When downloading/installing, it is recommended to read terms, explore possible options, and use the "Custom/Advanced" settings to opt-out from all supplements. Intrusive advertisements appear legitimate, yet they redirect to various questionable sites (e.g., adult-dating, gambling, pornography, etc.).

Should users encounter such ads and/or redirects, they must check their devices and immediately remove all dubious applications and browser extensions/plug-ins detected. If your computer is already infected with MegaUnit, we recommend running a scan with Combo Cleaner Antivirus for macOS to automatically eliminate this adware.
