How to uninstall NetFunctionSearch adware?

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

What is NetFunctionSearch adware?

Typically, users download and install applications such as NetFunctionSearch unintentionally. Therefore, they are categorized as potentially unwanted applications. This app is distributed through a fake installer. It is important to mention that NetFunctionSearch functions both as advertising software (adware) and a browser hijacker.

NetFunctionSearch adware

NetFunctionSearch adware in detail

NetFunctionSearch generates advertisements and changes a web browser's settings. It displays banner ads, pop-ups, coupons surveys, or other ads. It is strongly recommended not to click on ads shown by NetFunctionSearch or similar apps - those ads might open untrustworthy websites or download (or install) unwanted software.

It is possible that NetFunctionSearch displays ads designed to open websites similar to "MALWARE DETECTED Action Required", "Error Code: #2c522hq8wwj791", "Receive iPhone 12", and other deceptive pages encouraging visitors to install some unwanted software or providing personal information (credit card details, names, surnames, and so on).

Fake search engines can show results generated by legitimate and questionable search engines. Also, they can show their own results. In one way or another, results provided by fake search engines should not be trusted - they may contain links to malicious pages, unwanted advertisements.

There is a high chance that NetFunctionSearch collects various information, including IP addresses, visited websites, entered search queries, credit card details, passwords, or other browsing-related and (or) sensitive data. What is worse, data collected by an app of this type may be misused for malicious purposes (e.g., to steal identities, hijack accounts).

Adware in general

Usually, the main purpose of adware is to generate revenue for its developer by displaying various advertisements. However, apps like NetFunctionSearch do more - they hijack browsers and possibly collect various information as well. More similar adware examples are FlexibleOrigin, AssistiveMode, and ExpandedActivity.

How did NetFunctionSearch install on my computer?

NetFunctionSearch is distributed through a fake installer. It gets installed through a fake Adobe Flash Player installer. Typically, fake installers are promoted on websites that use deceptive techniques to trick users into downloading them. It is important to know that fake installers can be malicious.

In other cases, users download or install applications like NetFunctionSearch through downloaders or installers for other programs. It is common that PUAs can be found in downloaders and installers as optional offers. Users agree to download or install offered PUAs when they do not change "Custom", "Manual", "Advanced", or other options.

Sometimes, users download or install potentially unwanted applications by clicking untrustworthy advertisements designed to run certain scripts. As a rule, advertisements capable of triggering downloads or installations appear on untrustworthy websites. It is worth mentioning that those ads can be used to promote dubious pages as well.

How to avoid installation of potentially unwanted applications?

It is strongly recommended not to use third-party installers or downloaders, torrent clients, eMule and other Peer-to-Peer networks, unofficial pages, and so on. Downloads should come from official websites and through direct links. Other sources can be used to distribute PUAs and malicious apps.

Also, it is advisable to examine downloaders and installers to see if they include offers to download or install unwanted apps. As mentioned previously, unwanted offers can be declined via "Advanced", "Custom," or other settings, or by unticking checkboxes. Typically, PUAs are distributed through downloaders and installers for freeware.

Additionally, it is recommended not to click advertisements that shady pages (or installed PUAs) display. They could be designed to download or install unwanted software or open potentially malicious sites. Unwanted, suspicious apps (plug-ins, add-ons, extensions) installed on a browser (and software of this kind installed on the operating system) should be removed.
