Also Known As: Ads by PortalFlow

What is PortalFlow?

PortalFlow is a rogue app categorized as adware, it also has browser hijacker qualities. Furthermore, software products within these categories are considered to be PUAs (Potentially Unwanted Applications).

PortalFlow adware

PortalFlow adware in detail

Adware enables the placement of third-party graphical content (e.g., pop-ups, banners, coupons, and other intrusive ads) on any visited website and/or different interfaces.

The displayed adverts diminish the browsing quality and endanger device/user safety. When clicked on, intrusive advertisements redirect to untrustworthy/malicious sites, and some can download/install software (e.g., PUAs) without user consent.

Browser hijackers reassign browsers' homepage, default search engine, and new tab/window URLs - to fake web searcher addresses. Hence, new browser tabs/windows opened and search queries typed into the URL bar - redirect to the promoted address.

Fake search engines usually cannot provide search results, so they redirect to Google, Yahoo, Bing, and other legitimate ones. Furthermore, browser hijackers use persistence-ensuring methods to prevent users from restoring their browsers.

What is more, most PUAs (adware and browser hijackers included) have data tracking abilities. Targeted information includes: URLs visited, webpages viewed, search queries typed, IP addresses, personally identifiable details, and so forth. The collected data is then monetized by being shared with and/or sold to third-parties.

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

Adware in general

MapperProgressCleanSearchUnitAnalogSampleSkilledValidConfigType, NetFunctionSearch, and AccessibleValue are some examples of adware. It appears legitimate and offers various functionalities, which are typically nonoperational.

In fact, this applies to nearly all PUAs. Unwanted applications can have harmful abilities, e.g., running intrusive ad campaigns, causing redirects, hijacking browsers, and collecting private data.

How did PortalFlow 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 system. Intrusive adverts proliferate PUAs as well. Once clicked on, the ads can execute scripts to download/install these applications without user permission. Some PUAs may also have "official" download sites.

How to avoid installation of potentially unwanted applications?

It is advised to research software before download/installation and only use official/verified download sources. Untrustworthy channels, e.g., unofficial and freeware sites, Peer-to-Peer sharing networks, etc. - often offer bundled content.

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

In case of encounters with such ads and/or redirects, the system must be checked and all suspect applications and browser extensions/plug-ins detected - immediately removed from it. If your computer is already infected with PortalFlow, we recommend running a scan with Combo Cleaner Antivirus for macOS to automatically eliminate this adware.
