How to remove CompactFilter adware and the advertisements it displays?

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

What is CompactFilter?

CompactFilter is an adware-type app that has browser hijacker abilities. Since most users download/install software products of this kind inadvertently, they are also categorized as PUAs (Potentially Unwanted Applications).

CompactFilter adware

CompactFilter adware overview

Adware can display intrusive advertisements (e.g., pop-ups, coupons, surveys, etc.) on visited webpages and/or other interfaces. In addition to diminishing browsing quality, these adverts also endanger device and user safety. The delivered ads promote various untrustworthy, deceptive, and malicious sites. Some intrusive ads are even capable of stealthily downloading/installing software (e.g., PUAs) - when clicked.

Browser hijackers cause redirects to fake search engines by setting their addresses as browsers' homepage, new tab/window, and default search engine URLs. Fraudulent web searchers are typically incapable of providing search results, so they redirect to legitimate search engines (e.g., Google, Yahoo, Bing, etc.). Furthermore, hijacker software tends to use persistence-ensuring tactics to prevent browser recovery.

What is more, both adware and browser hijackers are infamous for their data tracking activities. This software can record users browsing and search engine histories and collect sensitive information obtained from them (e.g., IP addresses, personally identifiable details, finance-related data, etc.). The gathered data is then shared with and/or sold to third-parties.

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

Potentially unwanted applications in general

MultiSetLeadingProtocol, and AdvancedServices are a few examples of apps similar to CompactFilter. PUAs (adware and browser hijackers included) usually look legitimate and lure users into download/installation with "useful" features, which are rarely operational. Functionality and user safety are irrelevant since the only aim of unwanted applications is to generate revenue for their developers.

How did CompactFilter install on my computer?

PUAs are spread via downloaders/installers of other programs; this technique is called "bundling". Rushed downloads/installations increase the risk of allowing bundled content into the device. Intrusive ads proliferate PUAs as well. Upon being clicked, the adverts can execute scripts to make downloads/installations without user consent. PUAs may also have "official" promotional/download pages.

How to avoid installation of potentially unwanted applications?

It is strongly advised to research software and download from official/verified sources. Untrustworthy download channels, e.g., unofficial and freeware websites, 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 genuine, yet they redirect to questionable sites (e.g., gambling, pornography, adult-dating, etc.).

In case of encounters with such adverts and/or redirects - inspect the system and immediately remove all suspicious applications and browser extensions/plug-ins. If your computer is already infected with CompactFilter, we recommend running a scan with Combo Cleaner Antivirus for macOS to automatically eliminate this adware.
