How to remove the UpgradeFilter adware and the ads it delivers?

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

What is UpgradeFilter?

UpgradeFilter is a rogue application, categorized as adware. Additionally, this app has browser hijacker qualities. It operates by running intrusive advertisement campaigns and making modifications to browser settings - to cause redirects to fake search engines.

Hence, with the UpgradeFilter application installed, users encounter undesirable/harmful adverts and are constantly redirected to illegitimate web searcher addresses. Furthermore, most adware and browser hijackers spy on users' browsing activity.

Since most users download/install UpgradeFilter inadvertently, it is classified as a PUA (Potentially Unwanted Application). This app has been distributed via fake Flash Player updates. It is noteworthy that fraudulent updaters can spread PUAs and malware (e.g., trojans, ransomware, etc.).

UpgradeFilter adware

UpgradeFilter adware in detail

Adware enables the placement of pop-ups, banners, surveys, coupons, and other intrusive ads on any visited website and/or different interfaces. These advertisements seriously diminish the browsing experience by overlaying page content and slowing down the browsing speed.

Furthermore, intrusive adverts pose a threat to device/user safety. They promote sale-based webpages (of both legitimate and fake products), rogue, deceptive/scam, and malicious sites. Some of these ads can 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 searchers. Therefore, with a browser hijacker installed: new tabs/windows opened and search queries typed into the URL bar - redirect to the promoted search engine. Illegitimate search engines usually cannot provide search results, so they redirect to Google, Bing, Yahoo, and other genuine ones.

Furthermore, browser hijackers can undo any changes users try to make to their browsers, and/or they restrict/deny access to the browser settings. Therefore, recovering a hijacked browser is impossible without removing the software affecting it.

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 shared with and/or sold to third-parties.

To summarize, the presence of unwanted software on devices can lead to system infections, severe privacy issues, financial losses, and even identity theft. Therefore, it is strongly advised to remove all suspect applications and browser extensions/plug-ins without delay.

Adware in general

AccessDefaultRemoteView, and IndexerProject are a few examples of adware. This software usually looks legitimate and promises nonexistent "useful" features. In fact, practically all PUAs lure users with offers of various functionaries, which are seldom operational.

The sole purpose of unwanted applications is to generate profit for the developers; they have no real value to users. Therefore, instead of delivering on any promises, PUAs can run intrusive advert campaigns, hijack browsers, cause redirects, and gather private data.

How did UpgradeFilter install on my computer?

PUAs are distributed via downloaders/installers of other products. This deceptive marketing method of packing regular software with unwanted or malicious additions - is termed "bundling". These supplements can be hidden within the "Custom/Advanced" settings or left unmentioned entirely.

By rushing through download/installation processes (e.g., ignoring terms, skipping steps and sections, using "Easy/Express" settings, etc.) - users risk inadvertently allowing bundled content into their devices, thereby endangering the systems with potential infections.

Intrusive advertisements are used to proliferate PUAs as well. Once clicked on, the adverts can execute scripts to download/install these applications without user consent. Select PUAs also have "official" promotional webpages from which they can be downloaded.

How to avoid installation of potentially unwanted applications?

It is recommended to research software prior to download/installation. Furthermore, all downloads must be performed from official and verified sources. Dubious download channels, e.g., unofficial and free file-hosting sites, Peer-to-Peer sharing networks, and other third-party downloaders - often offer bundled and/or dangerous content.

Download and installation processes must be approached with care. Therefore, it is advised to read terms, study available options, use the "Custom/Advanced" settings to decline downloading/installing additional apps, tools, functions, and so on.

It is just as important to exercise caution browsing. Intrusive advertisements appear ordinary and harmless; however, they redirect to highly questionable and unreliable websites (e.g., adult-dating, pornography, gambling, and many others).

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