Fake Avg Antivirus extension removal instructions

What is the fake Avg Antivirus extension?

The fake Avg Antivirus extension is a piece of rogue software that is presented as a product of AVG AntiVirus, supposedly designed to protect browsers from various threats. This browser extension is fake and unable to perform the promised functionalities. Additionally, it collects browsing-related information. This illegitimate software may also operate as adware, i.e., run intrusive advertisement campaigns. Furthermore, content like the fake Avg Antivirus is often distributed alongside other PUAs (Potentially Unwanted Applications). Hence, with this browser extension installed, it is likely that additional adware, browser hijackers, or other harmful software has infiltrated the system.

Adware operates by enabling the placement of pop-ups, banners, surveys, coupons, full-page, and other intrusive ads - on any visited website and/or different interfaces. The delivered adverts overlay webpages and slow down the browsing speed, thereby seriously crippling the browsing experience. These advertisements are misleading, deceptive, and may even be malicious. They promote a variety of sale-oriented, rogue, untrustworthy, deceptive/scam, compromised, and malicious sites. However, by clicking on such ads, users risk more than just being redirected to the aforementioned websites. Some intrusive advertisements can be triggered to execute scripts designed to stealthily download/install software (e.g., PUAs).

Browser hijackers modify browsers in order to promote fake search engines. They assign illegitimate web searcher addresses as browsers' default search engine, new tab/window, and homepage URLs. Hence, with a browser hijacker installed: new browsers tabs/windows opened and web searches performed via the URL bar - redirect to the promoted search engine's address. Fake web searchers usually cannot provide search results, so they tend to redirect (or cause redirection chains leading) to Google, Bing, Yahoo, and other legitimate search engines. This software can also ensure its persistence by resetting any changes users attempt to make to their browsers. Alternatively, browser hijackers can restrict or deny access to the browser settings outright. Therefore, it is impossible to restore an affected browser without removing the software hijacking it.

As mentioned in the introduction, this fake Avg Antivirus extension has data tracking abilities. That is typical of all PUAs (adware and browser hijackers included). They target the following information: visited URLs, viewed pages, searched queries, IP addresses/ geolocations, personally identifiable details, and so on. PUA developers monetize the gathered data by sharing it with and/or selling it to third-parties (potentially, cyber criminals). To summarize, the presence of unwanted software on devices can lead to system infections, severe privacy issues, financial losses, and even identity theft. It is strongly recommended to immediately remove all suspicious applications and browser extensions/plug-ins - to ensure device integrity and user safety.

The Internet is full of deceptive/scam content and software. Illegitimate products are often disguised with or reference the names of genuine software and its developers. The fake "Google Translate" and "Google Docs" browser extensions illustrate this. And Windows ManagerShopping LoversVideo ExplorerBookLotVideo Ads Blocker - are some examples of adware. All types of PUAs entice users into download/installation with promises of "useful" and "advantageous" functionalities. However, the features seldom work as advertised, and in most cases - they are utterly nonoperational. The sole aim of unwanted software is to generate revenue for its developers. Therefore, instead of delivering on any promises, PUAs can run intrusive advert campaigns, hijack browsers, force-open untrustworthy/malicious sites, and collect private information.

How did the fake Avg Antivirus extension install on my computer?

PUAs are spread through downloaders/installers of other products. This false marketing technique of packing regular software with unwanted or malicious additions - is called "bundling". Rushed download/installation processes (e.g., ignored terms, skipped steps and sections, used "Easy/Express" settings, etc.) increase the risk of allowing bundled content into the system. Intrusive advertisements are also used to proliferate PUAs. Once clicked on, the ads can execute scripts to make downloads/installations without user consent. Some PUAs have "official" promotional/download webpages as well.

How to avoid installation of potentially unwanted applications?

It is important to research software prior to download/installation and/or purchase. Additionally, all downloads must be done from official and verified sources. Dubious download channels, e.g., unofficial and free file-hosting websites, Peer-to-Peer sharing networks, and other third-party downloaders - often offer dangerous and/or bundled content. When downloading/installing, it is advised to read terms, study all possible options, use the "Custom/Advanced" settings, and opt-out from supplementary apps, tools, features, etc. Intrusive adverts appear ordinary and harmless; however, they redirect to various unreliable and questionable sites (e.g., gambling, adult-dating, pornography, and so forth). In case of encounters with ads and/or redirects of this kind, 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 fake Avg Antivirus extension, we recommend running a scan with Combo Cleaner Antivirus for Windows to automatically eliminate this adware.
