How to uninstall FlexInterval adware from the operating system?

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

What is FlexInterval?

FlexInterval is an adware-type application with browser hijacker abilities. Due to the questionable techniques used to promote apps of this kind, they are also deemed to be PUAs (Potentially Unwanted Applications).

FlexInterval adware

FlexInterval adware overview

Adware enables the placement of third-party graphic content (e.g., pop-ups, banners, etc.) on any visited website and/or different interfaces. The displayed advertisements affect the browsing experience by limiting page visibility and slowing down the browsing speed.

Furthermore, these ads endanger device/user safety. Once clicked on, intrusive adverts redirect to unreliable/malicious sites, and some can download/install software (e.g., PUAs) stealthily.

Browser hijackers assign fake search engine addresses as browser's default, and also as their homepage and new tab/window URLs. Hence, search queries typed into the URL bar and new tabs/windows opened - redirect to the promoted address.

These search engines are typically incapable of generating search results, so they redirect to Google, Bing, Yahoo, and other legitimate ones. What is more, browser hijackers tend to use persistence-ensuring techniques to complicate their removal.

Most PUAs can track data, and FlexInterval is not an exception. Information of interest includes: browsing data, IP addresses, personally identifiable details, log-in credentials (usernames/passwords), banking information, etc. The collected data is then monetized by being shared with and/or sold to third-parties.

To summarize, the presence of unwanted software on devices can cause system infections, serious privacy issues, financial losses, and identity theft.

Adware in general

AddCloudFlexProduct, and DiscoveryHandler are a couple examples of apps within the adware category. They appear ordinary and harmless. Additionally, this software tends to offer "handy" features, which are usually nonoperational. In fact, functionality and user safety are irrelevant to practically all PUAs. The sole goal of unwanted applications is to profit at user expense.

How did FlexInterval install on my computer?

PUAs can be downloaded/installed together with other programs. The marketing technique of packing regular software with various supplements - is called "bundling". Intrusive advertisements are also used to spread PUAs. Upon being clicked, the adverts can download/install these apps without user consent. PUAs may have "official" download sites as well.

How to avoid installation of potentially unwanted applications?

It is strongly recommended to research software and use official/verified download channels. Dubious sources, e.g., unofficial and freeware websites, Peer-to-Peer sharing networks, etc. - can offer bundled content.

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

In case of encounters with adverts and/or redirects of this type, 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 FlexInterval, we recommend running a scan with Combo Cleaner Antivirus for macOS to automatically eliminate this adware.
